/* styles.css
 *
 * Shared stylesheet for the So Dental marketing website (landing page +
 * privacy / terms / support pages).
 *
 * Brand tokens are taken straight from the app's design system
 * (global.css / lib/theme.ts, ledger.md §16):
 *   primary orange  #D85A30   ink  #1a1a1a   cream/warm backgrounds
 * The display face is the Didot-style serif used in the "so dental"
 * app icon and the marketing posters; body copy uses the same system
 * font stack the app ships with. No web fonts are loaded, so the site
 * is fast, self-contained, and renders the real Didot on Apple devices.
