/*
=====================================================
BAQUEANO — Panel de acceso con Google (perfil.html)
=====================================================

PROPÓSITO:
  Dar al Website público un punto de entrada real de autenticación con
  Firebase Auth (Google). Antes, "Iniciar sesión" llevaba a un perfil de
  ejemplo sin ningún botón de acceso.

ARQUITECTURA:
  Estilos aislados con prefijo .bq-auth- para no chocar con las 70+ hojas
  existentes. Usa la paleta oficial (#165D6F, #F65E01, #F4E6C1, #0F172A).
  El botón de Google respeta las pautas de marca de Google (fondo blanco,
  logotipo "G" a color, texto "Continuar con Google").

ACCESIBILIDAD:
  Objetivos táctiles ≥ 48 px, foco visible, contraste AA, mensajes de error
  en región role="alert" y animaciones desactivadas con prefers-reduced-motion.

RELACIÓN:
  js/auth-panel.js (lógica), js/user-session.js (BaqueanoSession).
