/* ============================================================================
   talk2doc — landing pública (/)
   ============================================================================

   PROCEDENCIA. La base de este fichero es el sistema visual del prototipo
   `docs/talk2doc Web App (offline).html`, pasado por un acotador que prefija
   CADA selector con `body:has(.t2d-landing)`.

   POR QUÉ ESE PREFIJO, Y POR QUÉ NO SE PUEDE QUITAR. `index.html` y
   `drive.html` extienden el MISMO `base.html`. Este fichero solo lo carga
   `index.html`, pero se carga DESPUÉS de `pibico.css` y `collab.css`, y el
   CSS del prototipo trae reglas de elemento desnudo (`html`, `body`, `*`,
   `a`, `h1`-`h4`, `button`) y redefine clases compartidas (`.app-header`,
   `.app-footer`, `.app-main`, `.field`, `.avatar-btn`). Sin el prefijo, la
   landing quedaría bien y cualquier otra cosa que use esas clases, no.

   QUÉ SE DESCARTÓ DEL PROTOTIPO, A PROPÓSITO:
   · `.slide-panel` / `.panel-backdrop` — el prototipo los da con
     `z-index:201`. En producción son 1500 porque `.app-header` es 1400;
     adoptarlo metería los paneles DEBAJO de la navbar. Los aporta
     `collab.css`, que también carga aquí.
   · `.pibico-badge-*` y `.thin-scroll` — ya están en `pibico.css`.

   Los tokens `--bg-paper`, `--ink`, `--ink-deep` y las 8 rampas pastel viven
   dentro del ámbito de la landing, NO en `pibico.css`: ese fichero es
   byte-idéntico en api_auth, api_talk2doc y api_script, y tocarlo rompería
   la paridad entre servicios.
