/*
 * Landing de venta — hoja de estilos ESTÁTICA e independiente de la SPA.
 *
 * Parte de los MISMOS tokens HSL de la SPA (`src/styles/theme.css`, §11.1): navy de
 * marca, azul de acento y fuentes del sistema (la SPA usa la misma pila), para que el
 * paso landing → app no resulte brusco. Sin Tailwind, sin dependencias, sin fuentes
 * externas.
 *
 * LANDING_REDISENO 2026-10-15 — tema claro/oscuro:
 *   - `:root` = claro. Oscuro por `prefers-color-scheme` (CSS puro, también sin JS) salvo
 *     que el visitante haya elegido claro (`[data-theme="light"]`), y por
 *     `[data-theme="dark"]` (elección explícita; la fija un script del <head> antes del
 *     primer pintado con la clave `ui-theme` de la SPA).
 *   - Los dos temas están diseñados (no invertidos) y sus pares de texto se comprueban
 *     AA en `src/__tests__/landing-contrast.spec.ts`.
 *   - Animaciones solo con transform/opacity y SOLO con `prefers-reduced-motion:
 *     no-preference`; ninguna en bucle infinito.
