/* Shared styling for the static legal pages (policy.html, terms.html).
 *
 * These pages live in public/ and are copied verbatim by Vite, so they cannot
 * import src/app.css through the bundler. The design tokens below are therefore
 * a deliberate copy of the ones in src/app.css — keep them in sync if the brand
 * colours change. Same plain-<link> approach notepad-web/public already uses.
 *
 * Both languages are present in the HTML at once. English is visible by
 * default so the page is fully readable with JavaScript disabled (Google's
 * OAuth reviewers and crawlers must be able to read it); the inline script in
 * each page flips [data-lang] to switch.
