/* FASE NUEVE — F9 Sonic Studio · Audio y Sonido (C06: página principal, 6 subcategorías y 18 tipos).
   Se carga DESPUÉS de pc-gamer-v01.css, cuyo motor (pc-gamer-v01.js) ya aporta el parallax multicapa, la inclinación 3D
   (aquí siempre «soft»: máx. 3°), el revelado progresivo y el desplazamiento accesible. Esta hoja añade la portada en capas
   con fotos de audio, la onda sonora SVG (trazos animados solo con CSS, sin JavaScript extra y sin ningún sonido), las seis
   categorías, las tres experiencias y el banner del catálogo. Las animaciones continuas solo corren con la portada visible,
   se apagan en móviles/táctiles y desaparecen con prefers-reduced-motion. */
