/*
 * DriftwoodXI site styles — the launcher's driftwood/ocean tokens
 * (DriftwoodXI-Launcher src/renderer/src/theme/tokens.css) carried to the web,
 * so the site and the launcher read as one product.
 *
 * The type is the launcher's too, and self-hosted rather than pulled from
 * Google Fonts: the CSP in security.ts is `default-src 'self'` with no font-src
 * of its own, so a third-party font URL is simply blocked — and even if it were
 * allowed, a CDN round-trip on every page load to render a wordmark is a poor
 * trade. These are byte-identical to the launcher's own @fontsource files, so
 * the two products render the name from the same outlines.
