 * GSD theme — mirrors the Omics Portal design system (Manrope + Fraunces, warm
 * off-white surfaces, #cb333b red). Tokens are RAW OKLCH triplets (L C H) so the
 * Tailwind v3 config can wrap them as `oklch(var(--token) / <alpha-value>)` and
 * opacity utilities (bg-primary/80, …) keep working. Dark tokens follow either a
 * `.dark` class or the portal's `[data-bs-theme="dark"]`, ready for embedding.
