 Para simplificar el flujo de trabajo, el repositorio incluye varios **alias de Cargo** declarados en
 `.cargo/config.toml`. Basta con ejecutarlos desde la raíz del proyecto:
 
-| Comando | Descripción |
-| ------- | ----------- |
-| `cargo ts` | Ejecuta los tests de `pagetop` (*unit + integration*) con la *feature* `testing`. |
-| `cargo ts --test util` | Lanza sólo las pruebas de integración del módulo `util`. |
-| `cargo ts --doc locale` | Lanza las pruebas de la documentación del módulo `locale`. |
-| `cargo tw` | Ejecuta los tests de **todos los paquetes** del *workspace*. |

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or

+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including

+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"

+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+
+## 🧭 Sobre PageTop
+
+[PageTop](https://docs.rs/pagetop) es un entorno de desarrollo que reivindica la esencia de la web
+clásica para crear soluciones web SSR (*renderizadas en el servidor*) modulares, extensibles y
+configurables, basadas en HTML, CSS y JavaScript.
+
+
+## ⚡️ Guía rápida
+
+**Añade la dependencia** a tu `Cargo.toml` activando el motor de base de datos que necesites:
+
+```toml
+[dependencies]
+pagetop-seaorm = { version = "...", features = ["sqlite"] }
+```
+
+Las *features* disponibles son `mysql`, `postgres` y `sqlite`.
+
+**Configura la conexión** en el archivo de configuración de la aplicación:
+
+```toml
+[database]
+db_type = "sqlite"
+db_name = "my_app.db"
+max_pool_size = 5
+```
+
+Para MySQL o PostgreSQL añade también `db_user`, `db_pass` y `db_host`. El campo `db_port` es
+opcional; si se omite se usa el puerto predeterminado del motor.
+
+**Declara la extensión** en tu aplicación o en la extensión que la requiera:
+
+```rust,ignore
+use pagetop::prelude::*;
+use pagetop_seaorm::install_migrations;
+
+mod migration;
+
+struct MyApp;
+
+impl Extension for MyApp {
+    fn dependencies(&self) -> Vec<ExtensionRef> {
+        vec![
+            &pagetop_seaorm::SeaORM,
+        ]
+    }
+
+    fn initialize(&self) {
+        install_migrations!(m20240101_000001_create_users_table);
+    }
+}
+
+#[pagetop::main]
+async fn main() -> std::io::Result<()> {
+    Application::prepare(&MyApp).run()?.await
+}
+```
+
+**Escribe las migraciones** usando la API de [`migration`]:
+
+```rust,no_run
+// src/migration/m20240101_000001_create_users.rs
+use pagetop_seaorm::migration::*;
+
+pub struct Migration;
+
+#[async_trait::async_trait]
+impl MigrationTrait for Migration {
+    async fn up(&self, manager: &SchemaManager) -> Result<(), DbErr> {
+        manager
+            .create_table(
+                table_auto(Users::Table)
+                    .col(pk_auto(Users::Id))
+                    .col(string_uniq(Users::Email))
+                    .col(string(Users::Name))
+                    .to_owned(),
+            )
+            .await
+    }
+}
+
+#[derive(DeriveIden)]
+enum Users {
+    Table,
+    Id,
+    Email,
+    Name,
+}
+```
+
+**Define las entidades** en un módulo `entity/` usando las macros de derivación de [`db`]:
+
+```rust,no_run
+// src/entity/user.rs
+use pagetop_seaorm::db::*;
+
+#[derive(Clone, Debug, DeriveEntityModel, PartialEq)]
+#[sea_orm(table_name = "users")]
+pub struct Model {
+    #[sea_orm(primary_key)]
+    pub id: i32,
+    pub email: String,
+    pub name: String,
+}
+
+#[derive(Clone, Copy, Debug, DeriveRelation, EnumIter)]
+pub enum Relation {}
+
+impl ActiveModelBehavior for ActiveModel {}
+```
+
+**Opera con la base de datos** pasando la conexión [`db::dbconn()`] a cada consulta:
+
+```rust,ignore
+use pagetop_seaorm::db::*;
+
+// Asumiendo que existe un módulo `user` con la entidad definida arriba.
+async fn example() -> Result<(), DbErr> {
+    // Listar todos los registros:
+    let users = user::Entity::find().all(dbconn()).await?;
+
+    // Buscar por clave primaria:
+    let found = user::Entity::find_by_id(1).one(dbconn()).await?;
+
+    // Insertar un registro:
+    let new_user = user::ActiveModel {
+        email: Set("alice@example.com".to_owned()),
+        name: Set("Alice".to_owned()),
+        ..Default::default()
+    };
+    user::Entity::insert(new_user).exec(dbconn()).await?;
+    Ok(())
+}
+```
+
+
+## 📚 Créditos
+
+Este *crate* se apoya en bibliotecas del ecosistema [SeaQL](https://github.com/SeaQL) como:
+
+* [SeaORM](https://www.sea-ql.org/SeaORM), ORM asíncrono que usa internamente
+  [SQLx](https://github.com/launchbadge/sqlx) para el acceso y la ejecución de consultas a la base
+  de datos.
+
+* [SeaQuery](https://github.com/SeaQL/sea-query), generador de consultas SQL sobre el que se
+  construye el motor de migraciones y los *helpers* de esquema.
+
+* [sea-schema](https://github.com/SeaQL/sea-schema), librería de introspección de esquemas SQL,
+  usada por el módulo de migraciones para interrogar la estructura real de la base de datos (tablas,
+  columnas, índices y claves externas).
+
+El módulo de migraciones (`src/migration/`) incorpora una adaptación de
+[sea-orm-migration](https://crates.io/crates/sea-orm-migration). El código que se integra procede de
+la versión [**1.1.20**](https://github.com/SeaQL/sea-orm/tree/1.1.20/sea-orm-migration) en lugar de
+usarlo como dependencia ya que su paradigma de CLI no es compatible con el ciclo de vida de las
+extensiones de PageTop, donde las migraciones deben ejecutarse durante la inicialización de cada
+extensión. Los ficheros adaptados del original son:
+
+| Archivos              | Observaciones                                                            |
+|-----------------------|--------------------------------------------------------------------------|
+| `lib.rs`              | Incluido en `migration.rs`, descarta módulos y exportaciones del CLI     |
+| `connection.rs`       | Integración completa                                                     |
+| `manager.rs`          | Adapta *features* propias                                                |
+| `migrator.rs`         | Adapta *features* propias y omite gestión de errores del CLI             |
+| `prelude.rs`          | Absorbido en `migration.rs`, descarta exportaciones del CLI              |
+| `schema.rs`           | Integra con ajustes, adaptado de [loco](https://github.com/loco-rs/loco) |
+| `seaql_migrations.rs` | Integración completa                                                     |
+
+
+## 🚧 Advertencia
+
+**PageTop** es un proyecto personal para aprender [Rust](https://www.rust-lang.org/es) y conocer su
+ecosistema. Su API está sujeta a cambios frecuentes. No se recomienda su uso en producción, al menos
+hasta que se libere la versión **1.0.0**.
+
+
+## 📜 Licencia
+
+El código está disponible bajo una doble licencia:
+
+  * **Licencia MIT**
+    ([LICENSE-MIT](LICENSE-MIT) o también https://opensource.org/licenses/MIT)
+
+  * **Licencia Apache, Versión 2.0**
+    ([LICENSE-APACHE](LICENSE-APACHE) o también https://www.apache.org/licenses/LICENSE-2.0)
+
+Puedes elegir la licencia que prefieras. Este enfoque de doble licencia es el estándar de facto en
+el ecosistema Rust.

+//! Definición de entidades y acceso a la base de datos.
+//!
+//! Agrupa los *traits*, macros y tipos del sistema de entidades de SeaORM, junto con las funciones
+//! [`dbconn`], [`execute`], [`fetch_all`] y [`fetch_one`], en una sola importación:
+//!
+//! ```rust
+//! use pagetop_seaorm::db::*;
+//! ```
+//!
+//! El sistema de entidades (`Entity::find()`, `Entity::insert()`, transacciones) es el camino
+//! recomendado para la mayoría de operaciones. Las funciones [`execute`], [`fetch_all`] y
+//! [`fetch_one`] ofrecen vías alternativas para cuando ese sistema no es suficiente, como consultas
+//! sin entidad concreta, SQL específico para el motor de base de datos utilizado o sentencias
+//! puntuales.
+//!
+//! Estas funciones integran los valores como literales escapados, no como parámetros de base de
+//! datos. Para consultas con datos del usuario, el sistema de entidades es más robusto. Si aun así
+//! se necesita SQL en crudo con parámetros reales, se puede construir un [`api::Statement`]
+//! directamente con [`api::Statement::from_sql_and_values`].
+//!
+//! ## Tipos esenciales
+//!
+//! Destacan los siguientes elementos de uso más frecuente:
+//!
+//! - **Acceso**: [`DatabaseConnection`], [`dbconn`] (para obtener el pool de conexiones).
+//! - **Consultas**: [`EntityTrait`], [`QueryFilter`], [`QueryOrder`], [`QuerySelect`].
+//! - **Transacciones**: [`TransactionTrait`], [`DatabaseTransaction`].
+//! - **Modelos activos**: [`ActiveModelTrait`], [`ActiveValue`] ([`ActiveValue::Set`],
+//!   [`ActiveValue::Unchanged`], [`ActiveValue::NotSet`]).
+//! - **Macros de derivación**: [`DeriveEntityModel`], [`DeriveColumn`], [`DerivePrimaryKey`],
+//!   [`DeriveRelation`], [`EnumIter`].
+//! - **Errores**: [`DbErr`].
+//! - **Resultados**: [`QueryResult`] (filas sin tipar), [`ExecResult`] (INSERT/UPDATE/DELETE).
+//!
+//! ## Definir una entidad
+//!
+//! ```rust
+//! use pagetop_seaorm::db::*;
+//!
+//! #[derive(Clone, Debug, PartialEq, DeriveEntityModel)]
+//! #[sea_orm(table_name = "users")]
+//! // El struct debe llamarse `Model`: es un requisito de `DeriveEntityModel`.
+//! pub struct Model {
+//!     #[sea_orm(primary_key)]
+//!     pub id: i32,
+//!     pub email: String,
+//!     pub name: String,
+//! }
+//!
+//! #[derive(Clone, Copy, Debug, EnumIter, DeriveRelation)]
+//! pub enum Relation {}
+//!
+//! // `DeriveEntityModel` genera también `ActiveModel`, `Entity`, `Column` y `PrimaryKey`.
+//! impl ActiveModelBehavior for ActiveModel {}
+//! ```
+//!
+//! ## Operaciones CRUD
+//!
+//! ```rust,ignore
+//! use pagetop_seaorm::db::*;
+//!
+//! // El código asume que existe un módulo `user` con una entidad SeaORM definida.
+//!
+//! async fn example() -> Result<(), DbErr> {
+//!     // Buscar todos los registros.
+//!     let users = user::Entity::find().all(dbconn()).await?;
+//!
+//!     // Buscar con filtro.
+//!     let alices = user::Entity::find()
+//!         .filter(user::Column::Name.eq("Alice"))
+//!         .all(dbconn())
+//!         .await?;
+//!
+//!     // Buscar por clave primaria.
+//!     let found = user::Entity::find_by_id(1).one(dbconn()).await?;
+//!
+//!     // Insertar.
+//!     let model = user::ActiveModel {
+//!         name: ActiveValue::Set("Alice".into()),
+//!         ..Default::default()
+//!     };
+//!     user::Entity::insert(model).exec(dbconn()).await?;
+//!
+//!     // Actualizar: campos con `ActiveValue::Set`, clave primaria con `ActiveValue::Unchanged`.
+//!     let patch = user::ActiveModel {
+//!         id: ActiveValue::Unchanged(1),
+//!         name: ActiveValue::Set("Bob".into()),
+//!         ..Default::default()
+//!     };
+//!     patch.update(dbconn()).await?;
+//!
+//!     // Eliminar por clave primaria.
+//!     user::Entity::delete_by_id(1).exec(dbconn()).await?;
+//!
+//!     // Transacción. `Box::pin` es necesario: `TransactionTrait` exige `Pin<Box<dyn Future>>`.
+//!     dbconn().transaction::<_, DbErr, _>(|txn| Box::pin(async move {
+//!         user::Entity::insert(
+//!             user::ActiveModel { name: ActiveValue::Set("Carol".into()), ..Default::default() }
+//!         ).exec(txn).await?;
+//!         user::Entity::delete_by_id(2).exec(txn).await?;
+//!         Ok(())
+//!     })).await?;
+//!     Ok(())
+//! }
+//! ```
+//!
+//! Para migraciones y definición de esquemas usa [`migration`](crate::migration).
+//!
+//! ## Acceso completo a SeaORM
+//!
+//! El módulo [`api`] re-exporta el crate `sea_orm` íntegro bajo ese alias. Úsalo cuando necesites
+//! un tipo o función que no esté expuesto directamente en `db::*`:
+//!
+//! ```rust
+//! use pagetop_seaorm::db::api;
+//!
+//! // Tipos o utilidades no incluidos en db::*:
+//! let _: api::DatabaseBackend = api::DatabaseBackend::Sqlite;
+//! ```
+//!
+//! ## Construcción de consultas en tiempo de ejecución
+//!
+//! El módulo [`query`] re-exporta `sea_query` para construir las sentencias SQL que se pasan a
+//! [`fetch_all`] y [`fetch_one`]. Es el compañero natural de esas funciones dentro del módulo `db`:
+//!
+//! ```rust
+//! use pagetop_seaorm::db::*;
+//! use pagetop_seaorm::db::query::*;
+//!
+//! async fn example() -> Result<(), DbErr> {
+//!     let stmt = Query::select()
+//!         .column(Asterisk)
+//!         .from(Alias::new("users"))
+//!         .to_owned();
+//!     let rows = fetch_all(&stmt).await?;
+//!     Ok(())
+//! }
+//! ```

+
+## 🧭 Sobre PageTop
+
+[PageTop](https://docs.rs/pagetop) es un entorno de desarrollo que reivindica la esencia de la web
+clásica para crear soluciones web SSR (*renderizadas en el servidor*) modulares, extensibles y
+configurables, basadas en HTML, CSS y JavaScript.
+
+
+## ⚡️ Guía rápida
+
+**Añade la dependencia** a tu `Cargo.toml` activando el motor de base de datos que necesites:
+
+```toml
+[dependencies]
+pagetop-seaorm = { version = "...", features = ["sqlite"] }
+```
+
+Las *features* disponibles son `mysql`, `postgres` y `sqlite`.
+
+**Configura la conexión** en el archivo de configuración de la aplicación:
+
+```toml
+[database]
+db_type = "sqlite"
+db_name = "my_app.db"
+max_pool_size = 5
+```
+
+Para MySQL o PostgreSQL añade también `db_user`, `db_pass` y `db_host`. El campo `db_port` es
+opcional; si se omite se usa el puerto predeterminado del motor.
+
+**Declara la extensión** en tu aplicación o en la extensión que la requiera:
+
+```rust,ignore
+use pagetop::prelude::*;
+use pagetop_seaorm::install_migrations;
+
+mod migration;
+
+struct MyApp;
+
+impl Extension for MyApp {
+    fn dependencies(&self) -> Vec<ExtensionRef> {
+        vec![
+            &pagetop_seaorm::SeaORM,
+        ]
+    }
+
+    fn initialize(&self) {
+        install_migrations!(m20240101_000001_create_users);
+    }
+}
+
+#[pagetop::main]
+async fn main() -> std::io::Result<()> {
+    Application::prepare(&MyApp).run()?.await
+}
+```
+
+**Escribe las migraciones** usando la API de [`migration`]:
+
+```rust,no_run
+// src/migration/m20240101_000001_create_users.rs
+use pagetop_seaorm::migration::*;
+
+pub struct Migration;
+
+#[async_trait::async_trait]
+impl MigrationTrait for Migration {
+    async fn up(&self, manager: &SchemaManager) -> Result<(), DbErr> {
+        manager
+            .create_table(
+                table_auto(Users::Table)
+                    .col(pk_auto(Users::Id))
+                    .col(string_uniq(Users::Email))
+                    .col(string(Users::Name))
+                    .to_owned(),
+            )
+            .await
+    }
+}
+
+#[derive(DeriveIden)]
+enum Users {
+    Table,
+    Id,
+    Email,
+    Name,
+}
+```
+
+**Define las entidades** en un módulo `entity/` usando las macros de derivación de [`db`]:
+
+```rust,no_run
+// src/entity/user.rs
+use pagetop_seaorm::db::*;
+
+#[derive(Clone, Debug, DeriveEntityModel, PartialEq)]
+#[sea_orm(table_name = "users")]
+pub struct Model {
+    #[sea_orm(primary_key)]
+    pub id: i32,
+    pub email: String,
+    pub name: String,
+}
+
+#[derive(Clone, Copy, Debug, DeriveRelation, EnumIter)]
+pub enum Relation {}
+
+impl ActiveModelBehavior for ActiveModel {}
+```
+
+**Opera con la base de datos** pasando la conexión [`db::dbconn()`] a cada consulta:
+
+```rust,ignore
+use pagetop_seaorm::db::*;
+
+// Asumiendo que existe un módulo `user` con la entidad definida arriba.
+async fn example() -> Result<(), DbErr> {
+    // Listar todos los registros:
+    let users = user::Entity::find().all(dbconn()).await?;
+
+    // Buscar por clave primaria:
+    let found = user::Entity::find_by_id(1).one(dbconn()).await?;
+
+    // Insertar un registro:
+    let new_user = user::ActiveModel {
+        email: Set("alice@example.com".to_owned()),
+        name: Set("Alice".to_owned()),
+        ..Default::default()
+    };
+    user::Entity::insert(new_user).exec(dbconn()).await?;
+    Ok(())
+}
+```

+//! API para definir y ejecutar migraciones de base de datos.
+//!
+//! Cuando una extensión necesita persistir datos en una base de datos usando `pagetop_seaorm`,
+//! define sus migraciones en un submódulo `migration/` y las aplica al arrancar con la macro
+//! [`install_migrations!`](crate::install_migrations).
+//!
+//! Con una sola importación tienes todo lo necesario:
+//!
+//! ```rust
+//! use pagetop_seaorm::migration::*;
+//! ```
+//!
+//! # Convención de nombrado
+//!
+//! Cada migración es un módulo con el formato `m<YYYYMMDD>_<NNNNNN>_<nombre_descriptivo>`. El
+//! prefijo numérico garantiza el orden cronológico de aplicación:
+//!
+//! ```text
+//! src/
+//! └── migration/
+//!     ├── m20240101_000001_create_users.rs
+//!     └── m20240115_000002_add_email_index.rs
+//! ```
+//!
+//! # Estructura de una migración
+//!
+//! Cada archivo define un *struct* `Migration` que implementa [`MigrationTrait`]. El método `up`
+//! aplica el cambio; `down` lo revierte. Si no se implementa, devuelve un error; es **obligatorio**
+//! implementarlo si la extensión usa [`uninstall_migrations!`](crate::uninstall_migrations):
+//!
+//! ```rust,no_run
+//! // src/migration/m20240101_000001_create_users.rs
+//! use pagetop_seaorm::migration::*;
+//!
+//! pub struct Migration;
+//!
+//! #[async_trait::async_trait]
+//! impl MigrationTrait for Migration {
+//!     async fn up(&self, manager: &SchemaManager) -> Result<(), DbErr> {
+//!         manager
+//!             .create_table(
+//!                 table_auto(Users::Table)
+//!                     .col(pk_auto(Users::Id))
+//!                     .col(string_uniq(Users::Email))
+//!                     .col(string(Users::Name))
+//!                     .to_owned(),
+//!             )
+//!             .await
+//!     }
+//! }
+//!
+//! #[derive(DeriveIden)]
+//! enum Users {
+//!     Table,
+//!     Id,
+//!     Email,
+//!     Name,
+//! }
+//! ```
+//!
+//! # Seguimiento automático
+//!
+//! Las migraciones se mantienen en una tabla `seaql_migrations` de la base de datos. Cada migración
+//! aplicada queda registrada con su nombre y su marca de tiempo. Las migraciones ya aplicadas se
+//! omiten en ejecuciones posteriores.
+//!
+//! # Operaciones con `SchemaManager`
+//!
+//! El parámetro `manager` que recibe cada migración expone los métodos necesarios para
+//! modificar el esquema. Estos son los más habituales:
+//!
+//! | Método                                        | Acción                          |
+//! |-----------------------------------------------|---------------------------------|
+//! | [`SchemaManager::create_table`]               | Crea una tabla                  |
+//! | [`SchemaManager::drop_table`]                 | Elimina una tabla               |
+//! | [`SchemaManager::alter_table`]                | Modifica una tabla existente    |
+//! | [`SchemaManager::rename_table`]               | Renombra una tabla              |
+//! | [`SchemaManager::truncate_table`]             | Vacía una tabla                 |
+//! | [`SchemaManager::create_index`]               | Crea un índice                  |
+//! | [`SchemaManager::drop_index`]                 | Elimina un índice               |
+//! | [`SchemaManager::create_foreign_key`]         | Crea una clave foránea          |
+//! | [`SchemaManager::drop_foreign_key`]           | Elimina una clave foránea       |
+//! | [`SchemaManager::has_table`]                  | Comprueba si existe una tabla   |
+//! | [`SchemaManager::has_column`]                 | Comprueba si existe una columna |
+//! | [`SchemaManager::has_index`]                  | Comprueba si existe un índice   |
+//! | [`SchemaManager::create_type`] *(PostgreSQL)* | Crea un tipo personalizado      |
+//! | [`SchemaManager::alter_type`] *(PostgreSQL)*  | Modifica un tipo personalizado  |
+//! | [`SchemaManager::drop_type`] *(PostgreSQL)*   | Elimina un tipo personalizado   |
+//!
+//! # Funciones de esquema
+//!
+//! Las funciones de esquema disponibles simplifican la definición de columnas. Siguen el patrón
+//! `<tipo>(col)` (NOT NULL), `<tipo>_null(col)` (nulable) y `<tipo>_uniq(col)` (NOT NULL + UNIQUE).
+//! Algunos ejemplos:
+//!
+//! | Función             | SQL equivalente                                     |
+//! |---------------------|-----------------------------------------------------|
+//! | `table_auto(tabla)` | `CREATE TABLE IF NOT EXISTS` + timestamps           |
+//! | `pk_auto(col)`      | `INTEGER NOT NULL PRIMARY KEY` (con autoincremento) |
+//! | `pk_uuid(col)`      | `UUID NOT NULL PRIMARY KEY`                         |
+//! | `string(col)`       | `VARCHAR NOT NULL`                                  |
+//! | `string_null(col)`  | `VARCHAR NULL`                                      |
+//! | `string_uniq(col)`  | `VARCHAR NOT NULL UNIQUE`                           |
+//! | `integer(col)`      | `INTEGER NOT NULL`                                  |
+//! | `boolean(col)`      | `BOOLEAN NOT NULL`                                  |
+//! | `timestamp(col)`    | `TIMESTAMP NOT NULL`                                |
+//! | `uuid(col)`         | `UUID NOT NULL`                                     |
+//!
+//! Estas son sólo las funciones más habituales. El módulo [`schema`] define la lista completa, con
+//! variantes para `decimal`, `date`, `time`, `json`, `blob`, `binary`, `array`, `enumeration`,
+//! `char`, `interval` y sus formas `_null` y `_uniq`.
