   css/comercios-assistant.css — "Asistente IA" de Analista de Productos
   Chat propio (autocontenido — no depende del asistente flotante del
   núcleo general, este módulo es candidato a migrar a dominio propio).

   BUG REAL encontrado en vivo: antes usaba var(--ap-blue)/--ap-card/etc,
   que sólo existen dentro de #page-analista_productos. El modal se
   crea con document.body.appendChild(overlay) — FUERA de ese scope —
   así que todas esas variables quedaban sin valor: fondo transparente,
   texto sin color aplicado (heredaba negro del body), toda la ventana
   se veía como un bloque negro con texto apenas legible en un costado.
   Fix real: paleta 100% propia (--ca-*), definida acá mismo, que no
   depende de en qué parte del DOM se monte el widget. ─────────────── */
