/* ============================================================================
   Einbürgerungstest 2026 — production stylesheet
   Ported from the "Einbürgerungstest 2026 Design System" (tokens/ + components/).

   Design thesis: "amtlich, but friendly" — the visual language of a well-designed
   German official document. Flat, bordered, shadow-free, paper-like.
   Borders do the work, never elevation. Radius is 14px everywhere.
   RTL mirrors genuinely via logical properties — never scaleX.

/* Archivo is self-hosted, not loaded from the Google Fonts CDN. Two reasons:
   (1) the design system asks for it (readme.md → CAVEATS), and (2) embedding
   Google Fonts transmits the visitor's IP to Google without consent, which
   LG München I ruled a GDPR violation (3 O 17493/20, 20.01.2022). This site
   is German-facing, so the CDN is not an option.
   Variable font, weights 400–800. Latin + Latin-Ext only — Archivo has no
   Cyrillic or Arabic glyphs, so ru/uk/ar headings fall through to the system
   stack by design (see readme.md → VISUAL FOUNDATIONS). */
