+traves del catalogo activo de langs y renderiza el texto traducido.
+
+Familia con `<FormatDate>`, `<FormatNumber>`, `<RelativeTime>`: todos
+son wrappers tipados del runtime para que un audit i18n encuentre cada
+sitio que toca el catalogo con `grep "<Trans"`.
+
+## Superficie

+<!-- 5 modos de resolucion -->
+<Trans>#?common.save|Save</Trans>            <!-- children como idlangref -->
+<Trans value="#?common.save|Save" />          <!-- value prop -->

+<Trans path="common.greet" params={{name: 'Juan'}} />
+<Trans as="strong">#?ui.required|Required</Trans>
+<Trans path="common.save" locale="en-US">Save</Trans>
+```
+
+## Props clave
+
+| Prop | Tipo | Default | Notas |
+| --- | --- | --- | --- |
+| `value` | `LangString` | — | `idlangref` (`#?path\|fallback`) o literal. |
+| `path` | `string` | — | Dotted path al catalogo (ej. `'common.save'`). |
+| `params` | `Record<string, unknown>` | — | Interpolacion para `path`. |
+| `locale` | `SupportedLocale` | runtime | Override por instancia. |
+| `trim` | `boolean` | `true` | Trim del texto capturado de children. |
+| `as` | `keyof HTMLElementTagNameMap` | `'span'` | Tag HTML. |
+| `children` | snippet | — | Fallback / source si no hay `value` / `path`. |
+
+## Modos de resolucion
+
+| Modo | Forma | Source |
+| --- | --- | --- |
+| 1. Children-only | `<Trans>#?common.save\|Save</Trans>` | DOM `textContent` parseado como `idlangref`. |
+| 2. Value prop | `<Trans value="#?common.save\|Save" />` | `value` parseado. |
+| 3. Path + children fallback | `<Trans path="common.save">Save</Trans>` | `t(path)` con `children` como fallback si la key no existe. |
+| 4. Path + params | `<Trans path="common.greet" params={{name}} />` | `t(path, params)`. |
+| 5. Pass-through | `<Trans value="literal text" />` | Texto literal sin resolver. |
+
+## Decisiones
+
+- **Reactivo al locale**: el `$derived` re-corre cuando el locale activo
+  cambia. La lectura va a traves de `uix.langs.t / ts` que estan
+  acopladas al sistema reactivo de runes.
+- **Captura de children**: cuando ni `value` ni `path` estan
+  presentes, el componente captura `textContent` del nodo via
+  `bind:this={captureNode}` + `$effect`. La primera render emite el
+  children original (`#?path|fallback` sin resolver); en `$effect`
+  intercepta y resuelve.
+- **Cast del path**: `langs.t()` tipa su primer overload con
+  `${string}.${string}` (template literal estricto). Como el runtime
+  acepta paths dinamicos en runtime, se castea via
+  `Parameters<typeof t>[0]`.
+- **Fallback a children**: cuando `t(path)` devuelve el path original
+  (signal de "key no encontrada"), el componente cae al `capturedText`
+  si existe.
+- **No CSS recipe**: marker `[data-trans]` solo para tooling.
+- **No emite eventos sema**.
