/*
 * LinkDish public site: shared foundation for every page.
 * Tokens, light and dark themes, header, navigation, buttons, forms, FAQ, final call,
 * footer, mobile dock and motion. Page families add marketing.css (home + landing
 * pages) or info.css (support, privacy, invite, 404).
 *
 * Colors are semantic custom properties that mirror apps/web/src/styles/tokens.css.
 * Components use tokens only, so the dark theme is a token swap.
