/* NurPrivat — shared design system.
 *
 * Values are taken from the design handoff (design_handoff_nurprivat/README.md),
 * which is authoritative. Two deliberate deviations, both recorded here so nobody
 * "fixes" them back:
 *
 *   1. Contact address is kontakt@nurprivat.com, not the hallo@ in the handoff.
 *      kontakt@ is what Cloudflare Email Routing actually delivers, and it is the
 *      address named in the Impressum — a legally required field must not point
 *      at a mailbox that does not exist.
 *   2. No Google Fonts. Loading them from Google's CDN transmits the visitor's IP
 *      (LG München I, 20.01.2022) and is a documented GDPR violation with an
 *      Abmahnung wave behind it. System stacks only.
