-# Eidos Trans
-
-`<Trans>` es un **service component** — un wrapper greppable de
-`getActiveUix().langs.t / ts`. Resuelve un `idlangref` o un `path` a
-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
-
-```svelte
-<!-- 5 modos de resolucion -->
-<Trans>#?common.save|Save</Trans>            <!-- children como idlangref -->
-<Trans value="#?common.save|Save" />          <!-- value prop -->
-<Trans path="common.save">Save</Trans>        <!-- path + children=fallback -->
-<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**.
