/* ════════════════════════════════════════════════════════════════════════════
   chat-viewer.css — Visor de conversaciones (/chats · inbox del agente)
   ────────────────────────────────────────────────────────────────────────────
   Reemplaza el bloque <style> inline de ChatViewer.razor. Prefijo .wachat-*
   (mismos nombres que ya usa el markup) + los nuevos .wachat-cmp-* del
   compositor rico (emojis / adjuntos / audio).

   Los colores del CHROME (sidebar, modales, botones) usan tokens --gi-* de
   tokens.css para que sigan el tema de la app. Los colores de la SUPERFICIE
   DE CHAT (fondo con patrón, burbujas, ticks) son propios del visor y viven
   en las variables --wa-* de abajo, con override para data-theme="dark".
