/* Deviant brand layer — shared by every page under deviant.test / deviant.nav.
 *
 * Palette and type lifted from D:/Dev/Deviant/Parameters/webfiles/deviant_website.html
 * so pages built here sit next to the existing prototypes without a visual break.
 *
 * SELF-CONTAINED BY DESIGN. No @import, no CDN, no external font fetch. A page
 * using this file must render identically with the network unplugged — that is the
 * requirement for Sia-hosted sites, where there is no origin to fall back to.
 * To upgrade the typography, drop woff2 files into shared/fonts/ and the build
 * will emit the @font-face rules. See shared/fonts/README.md.
