/* =========================================================
   Loyca — hoja de estilos base
   Dirección "botánico minimalista": paleta y tipografías de referencia
   pasadas por el usuario 2026-09-01 (ejemplo "Cardenal"). El logo actual
   (images/logo.png, pájaro con panza naranja) es el definitivo.
   Pasada de diseño 2026-09-01 ("inmensamente especial"): hero a pantalla
   completa con marca de agua del pájaro, ornamento de hoja (motivo
   compartido de Arbolia) junto a cada título de sección, animaciones de
   scroll-reveal, sección de contacto invertida (oscura) como cierre.
   Pasada "vintage" 2026-09-03: misma paleta (ya aprobada), pero tipografía
   de póster (Anton para titulares/precio, Oswald para labels/nav/botones),
   grano de papel envejecido, bordes tipo ticket (dashed/double) y cintas —
   referencia: publicidad impresa de Loyca (LoycaVin2.png).
   Contenido de las secciones sigue en PLACEHOLDER.
