/* Shared styling for the Aprendaal public site (docs/), deployed to EAS Hosting by
   `npm run deploy:site`. Extracted from the original inline <style> in
   privacy-policy.html once the site grew past one page — the three pages must stay
   visually identical, and duplicating the block three times invites drift.

   Brand colors mirror src/theme.ts (NEUTRAL_PRIMARY #E07B00). Light and dark are
   both supported via prefers-color-scheme. No build step, no dependencies. */
