 * El Spa deja de ser una galería de capas cruzadas y se convierte en un filme:
 * una secuencia de fotogramas REALES (extraídos de los vídeos del salón) cuyo
 * cabezal de reproducción es el propio scroll. El filme inunda la pantalla a
 * sangre (sin marcos ni bordes), con una cámara continua de zoom y encuadre,
 * y el texto flota como tarjetas de título sobre la proyección. El aro abre,
 * el agua corre, las manos trabajan, la luz cambia y el tratamiento devuelve
 * a la parte luminosa.

/* ==========================================================================
   SPA CAPILAR · reconstrucción de la experiencia (capa de preview)
   --------------------------------------------------------------------------
   Qué se corrige y por qué:

   1. ENCUADRE. El filme es una secuencia vertical (540×960) que se proyectaba
      a sangre en un viewport horizontal: se escalaba ×2,67 y sólo se veía el
      35 % de su altura, así que el material se percibía como un vídeo mal
      proyectado. Pasa a ser una ventana vertical a la derecha, a escala casi
      nativa (×1,07 en 1440×900), con filete de cobre. La composición rimá con
      el hero: sujeto a la derecha, texto a la izquierda.

   2. CONTRASTE. La tipografía vivía sobre el fotograma y encima se atenuaba
      hasta opacidad 0,05–0,16 en los tránsitos (45 % del recorrido por debajo
      de 3:1). Ahora el texto vive en penumbra plana (desktop) y sobre un velo
      inferior cerrado (móvil), y el capítulo activo está SIEMPRE a opacidad
      plena: el relevo lo marca `is-active`, que el JS canónico conmuta de
      forma discreta, en lugar de una disolución continua.

   3. DURACIÓN. 620vh (5.580 px = 42 % del recorrido de la Home para 225
      caracteres) → 320vh. Cada capítulo respira sin eternizarse.

   4. CONTINUIDAD. Se suaviza la entrada con un velo cálido que se disuelve en
      los primeros compases (el salón se apaga) y se conserva la liberación
      luminosa hacia «El salón». Fuera el raíl decorativo «RITUAL / 04»: en su
      lugar, una barra de progreso con función real.

   No se toca CSS ni JS canónicos: todo son overrides de esta capa.
