/* ============================================
   Cascarón de navegación — richbm.app v2
   ============================================
   Especificación visual aprobada 2026-09-23. Todo sale de los tokens de
   styles.css (`:root` y `[data-theme="dark"]`), así el modo oscuro funciona
   sin reglas duplicadas. Nada de colores fijos acá.

   Se activa con `body.shell-on`, que pone shell.js. Sin esa clase la app se
   ve como antes — es el interruptor para volver atrás sin revertir nada. */
