 * Nordhort brand — design tokens as CSS variables.

 * names (Tiefsee, Stahlblau, ...) on purpose; they are the brand's own vocabulary.
 *
 * Fonts (SIL OFL): Space Grotesk (headings), Inter (body), JetBrains Mono (code /
 * technical values). Self-hosted from static/fonts/ — as long as no font files are
 * present, the respective system fallback applies (see static/fonts/README.md).
 * Deliberately no external font CDN (digital sovereignty).
