/* ---------------------------------------------------------------------------
 * bbai.css — las primitivas de la interfaz del ANALISTA (agente, ⌘K, hallazgos)
 * ---------------------------------------------------------------------------
 * Referencia: beautifului.dev (Turbo, MIT) — "Crafted primitives for AI-native
 * interfaces", 21 componentes. Miguel, 29 sep 2026: *"recheck and rework the
 * native interfaces que tenemos en bridgebi utilizando los copy prompts y todo
 * diseños de esta página"*. El código de cada uno se bajó del propio sitio (el
 * botón "Copy code" entrega el .tsx completo) y se leyó antes de portarlo.
 *
 * Lo que se trajo es la GEOMETRÍA y el RITMO, no la paleta:
 *   - su vocabulario de tokens (`--ink`, `--ink-2`, `--ink-3`, `--line`,
 *     `--surface`, `--inset`, `--field`, `--hover-2`, `--accent`, sombras
 *     `hairline/card/overlay`) es casi uno a uno el nuestro, así que cada regla
 *     de aquí usa `--bb-*` y el tema oscuro sale gratis;
 *   - su curva principal es cubic-bezier(.23,1,.32,1) — que YA es
 *     `--bb-ease-strong`. 48 de sus 58 transiciones la usan;
 *   - su escala de texto: 13px cuerpo, 12.5px filas, 11.5px metadatos, mono
 *     tabular para todo lo que cuenta. La mono de la casa es `--bb-mono`
 *     (ver ../DESIGN.md), NUNCA una familia escrita a mano.
 *
 * Este archivo es REAL del app, no del catálogo (misma regla que bbbar.css):
 * `/ui` lo enseña junto a lo que hay hoy, Miguel escoge, y la página que adopte
 * un default importa ESTE archivo. Prefijo `bbai-` para que no pueda tocar nada
 * de agent.css / index.html por accidente.
 *
 * `bbai-`, NUNCA `bba-`: el primer corte (29 sep 2026) salió con `bba-` y
 * announce.css (el pop-up de Anuncios) ya era dueño de ese prefijo — `.bba-card`,
 * `.bba-foot`, `.bba-x` chocaban en las dos direcciones: el bloque de código de
 * una respuesta salió a opacidad 0 con blur(8px) (el estado de ENTRADA del
 * pop-up) y el pop-up heredaba el pie y la X de aquí. Antes de estrenar un
 * prefijo: `grep -rn "\.<prefijo>-" *.css *.js`.
 *
 * Movimiento: un solo `@media (prefers-reduced-motion)` al pie congela TODO lo
 * que se repite (la rejilla, el brillo, los anillos). El reloj sigue corriendo
 * — un tiempo que avanza es información, no decoración.
