/* ==========================================================================
   Antlook · Hero holográfico en claro (laboratorio) — ronda 2
   Colores: tema claro del navegador, acento azul
   (src/styles/themes.css · [data-theme="light"][data-accent="blue"]).
   Escena: 800 × 560 u (1 u = 1/800 del ancho del escenario).
   Profundidad: suelo -60 u · ventana 0 · escudo 40 u · hologramas 100–220 u.
   Reloj: hero.js pone data-ch="0..3" en .ah cada 7 s (T = 28 s); el CSS hace
   el resto: transiciones de entrada/salida y animaciones de capítulo que
   arrancan al activarse el capítulo (nacen sincronizadas por construcción).
   Solo se animan transform / opacity (y un stroke-dashoffset puntual).
   Sin JS / movimiento reducido: composición estática completa (sin data-ch).
