/* Builgent Chatbot CSS standalone — MT, SOLO diseño (las clases las pone chatbot-mt.js)
   ═══════════════════════════════════════════════════════════════
   REDISEÑO 2026-07-02 — burbuja moderna brand-adaptive
   · Tokens --bgc-*: leen la paleta del HOST (--brasa/--rojo/--queso/--ff-d del
     template craft) con fallback neutro Builgent → el widget viste los colores
     del cliente sin tocar JS ni config. Host sin vars = look neutro premium.
   · Fixes auditados: z-index por ENCIMA del nav de la web (nav z:100 → bgc 117-119)
     y scroll del historial (.bgc-msgs min-height:0, el clásico de flexbox).
   · Fuera Instrument Serif (baneada por el playbook anti-slop): el display
     hereda la fuente display del host (--ff-d) o la del sistema.
