/* ==========================================================================
   VITA RAÍZ — Hoja única del sitio.

   Una sola hoja, en el orden en que se lee la página. Antes hubo cinco capas
   apiladas peleando la cascada; aquí no se apila nada: si algo hay que cambiar,
   se cambia en su sección.

   Reglas de la casa:
   - Un solo acento: azul acero. El resto es grafito, plata y blanco mineral.
   - El packshot no se altera nunca (ni filtro, ni recolor, ni recorte creativo).
   - Todo control táctil mide 48px como mínimo.
   - Nada se anima salvo opacity, transform y clip-path.
   ========================================================================== */
