/*
 * The "Gold control room" look (BRAND-001, 25-Sep-2026), carried from the homepage
 * (`src/app/home.css`, scoped `.rt-home`) onto the privacy, terms, support and
 * search pages, scoped `.rt-page` so the two stylesheets never collide. The
 * colour tokens, the gutter and the max content width are copied verbatim from
 * `.rt-home`'s own token block (`tests/unit/brand-page-stylesheet.test.ts` checks
 * that the values never drift apart). The homepage itself is untouched: this
 * file is never linked from it.
 *
 * Fonts: Unbounded, Instrument Sans and JetBrains Mono, the same latin-subset
 * variable files `next/font/google` already serves the homepage, self-hosted
 * here as static files so these pages make no request to a font service either.
 * All three families are distributed under the SIL Open Font License 1.1.
