   Arletex Design System v3.5 — Tela Blanca (/tela-de-colores/tela-blanca)
   Hoja editorial por página. Prefijo de clase y de token: tb- / --tb-*.
   Tokens locales con fallback a --ax-* global y, si no, a hex del sistema.
   ─────────────────────────────────────────────────────────────────────────
   El "blanco" es el TEMA, no el chrome: la marca sigue siendo orange/ink/paper.
   Reto particular: los TONOS son casi-blancos (mate, óptico, nieve, hueso,
   marfil). Las bandas/puntos de --tone llevan hairline ink para ser visibles
   sobre fondo blanco. Las fotos de tela blanca van sobre card con borde ink
   para no "desaparecer". Se respeta ≥55% blanco · ink como puntuación.
