/*
 * Stealth-gate cover pages (gate.html / gate-denied.html).
 *
 * The site's "Ledger" design language, inverted for an after-hours feel:
 * iron-gall ink becomes the page, ecru paper becomes the ink, and the crimson
 * double margin rule keeps its place at the left edge. Tokens mirror
 * src/styles/tokens.ts — these pages are static and load no bundle, so the
 * values are restated here.
