/* ============================================================
   Interact Savescreen — a product of Optexia
   Shared by every page (landing, legal pages, thank-you pages) and by the
   in-app copy of the legal pages (public/legal/, scripts/build-legal.mjs):
   Optexia's colour tokens (light and dark), header, footer, buttons and the
   sober content pages. The landing adds assets/landing.css; the fonts are in
   assets/fonts.css (Archivo + IBM Plex Mono, self-hosted).
   No framework, no CDN, no inline style (the CSP forbids it).
