/* Profile Switcher & Select Screen (Perfiles múltiples locales, Parte 2)

   Layout only - every visual building block (Avatar, Button) still comes
   from js/components/*.js (Fase 8). These rules arrange the profile
   grid/cards, the boot-time full-screen gate, and the avatar picker used
   by the create-profile form. Tokens only, no raw colors/shadows/radii/
   durations (CLAUDE.md reglas 79/80/81). */
