/* ============================================================
   Lotio — Landing pública
   ------------------------------------------------------------
   COLOR: sale de docs/producto/branding/tokens.css (Dark Luxe
   v0.3, validado por Lucas 2026-06-18). NO hardcodear HEX acá:
   si cambia un color, se cambia en tokens.css y se replica.

   COMPONENTES: capa estilo shadcn/ui escrita a mano sobre esos
   tokens (playbook 02_frontend-playbook.md §5). Se replica el
   lenguaje —Card, Badge, Button, Separator, Alert, ring de foco
   de 3px, escala de radios— SIN traer la librería: la landing es
   deliberadamente cero-dependencias.

   Sin dependencias externas a propósito: Meta rechaza la
   verificación si el sitio no carga, y cada recurso remoto es
   un modo de falla más.

   REGLA DE COLOR (01_sistema-de-color.md §3 y §4):
   proporción 75 negro / 15 azul / 10 ámbar. El ámbar va SOLO en
   títulos grandes, íconos, líneas, detalles y CTA — nunca en
   texto de cuerpo: sobre negro no llega a WCAG AA.
