   Rental Rosarito 2026 — Hero panorámico 3D

   Cuatro planos:
     1. .hero__fondos     panorámica 21:9 a sangre del slide activo (cruce +
                          Ken Burns + paralaje de puntero). Sin 3D.
     2. velo + sol + olas el sol dorado que late tras el horizonte y tres
                          líneas de marea que se dibujan al cargar.
     3. .hero__panorama   tarjetas en ARCO (ventanas de la casa) curvadas en
                          profundidad: la activa al frente y las siguientes
                          giran hacia atrás a la derecha. Aquí vive el preserve-3d.
     4. .hero__texto      titulares por RELEVO, fuera de cualquier contexto 3D.

   Trampas ya documentadas y evitadas:
     (1) max-width:none en fotos que deben desbordar su caja
     (2) velos FUERA del contexto preserve-3d
     (3) sin will-change en capas con foto
     (4) top:0 en paneles inactivos posicionados en absoluto
     (5) relevo de texto .3s / .6s + .3s, nunca cruce
     (6) overflow:clip (no hidden)
     (7) sin translateZ en el texto: agranda la caja y lo recorta
     (8) vector-effect: non-scaling-stroke en las olas estiradas
