/*
 * VooDooBox.ai brand overlay — the single hosted source of truth for the
 * product family's look and feel. Served at /brand/voodoobox.css from this
 * app (the portal); any product — Next.js, FastAPI/Jinja2, static HTML —
 * consumes it with a plain <link rel="stylesheet">. See docs/BRAND.md for
 * the versioning contract and the caveat about cross-origin dependence on
 * this app staying up.
 *
 * Palette derived from public/brand/logo-source.jpg: near-black background,
 * a red-orange wireframe mark, off-white wordmark. Three layers, in order:
 *   1. Tokens      — custom properties only, no selectors below :root.
 *   2. Base         — bare element styling (body, headings, links, forms).
 *   3. Components   — `vdb-` prefixed classes, safe to mix into any app's
 *                     own markup without colliding with its existing CSS.
 *
 * Font note: the wordmark uses a bold geometric sans that isn't self-hosted
 * here yet — embedding a real font file needs an actual licensed asset
 * chosen deliberately, not fabricated by this pass, and this machine sits
 * behind SSL inspection that breaks ad-hoc downloads from font CDNs (see the
 * project's norton-ssl-inspection note). Ships on a system-font stack for
 * now; swap --vdb-font-display once a real file lands in ./fonts/.
