/* Walkie Desk — web app (M5a): solo design token di /viewer/tokens.css (docs/WALKIE_DESK_UI.md §2).
 *
 * Stesse regole del viewer (viewer-web/style.css): niente colori, raggi, font, pesi o dimensioni di testo letterali.
 * Eccezioni ammesse: 0 e 1px; percentuali di layout (100%, 50%); soglie delle @media in px; numeri senza unità
 * (fattori di calc(), opacità, z-index, durate); `transparent` e `currentColor`; color-mix() solo fra token.
 * Codice QR: moduli `--wd-video-bg` (nero) su `--wd-on-primary` (bianco) in entrambi i temi, perché i lettori
 * di QR vogliono moduli scuri su fondo chiaro (servirebbero token propri: proposti nel report).
