/* ============================================================================
   ESCUELA DE BALLET RUSO — Hoja de estilos de componentes
   ----------------------------------------------------------------------------
   Tailwind aporta el layout (grid, spacing, breakpoints). Este archivo define
   los componentes con identidad propia: botones, arcos, carrusel, acordeón,
   formulario y animaciones.

   IMPORTANTE — capas en cascada:
   La declaración @layer de abajo replica el orden de Tailwind v4. Los estilos
   propios viven en la capa `components`, que va DESPUÉS del reset de Tailwind
   (base) y ANTES de sus utilidades. Así una utilidad suelta en el HTML
   (por ejemplo `mt-8`) siempre puede ajustar un componente sin pelear con él.
