/* ============================================================================
   PORTADA · kardfire.com/  y  /en
   ----------------------------------------------------------------------------
   Hoja de la portada estática (`landing/template.html`). No es la app: aquí no
   hay React Native ni `useThemeTokens()`, así que los tokens se copian como
   variables de CSS, y `styles.check.ts` comprueba que sigan siendo los de
   `core/theme/palette.ts` (tema oscuro, el de fábrica) — igual que hace con la
   pantalla de arranque de `public/index.html`.

   Lo mismo que en la app, por las mismas razones:
     - Neutros cálidos de tinta impresa; el oro (`mtg`) es el acento, y sobre él
       la tinta es el FONDO, nunca un blanco fijo (E-27).
     - Asap variable servida por nosotros, sin Google Fonts.
     - Radios por tamaño de caja (botón pill, panel 24, marco 32) y la esquina
       de una carta con `CARD_CORNER_RADIUS_RATIO`, nunca un radio fijo (E-68).
     - Foco visible siempre y `prefers-reduced-motion` respetado (E-86).
   Lo que es solo de la portada: los discos de maná pálidos (el color IMPRESO
   del símbolo, el de `MANA_COLOR_CONFIG`) marcan cada fortaleza.
