/* Tuck Here — shared site styles (2026-06-12 rebuild)
 *
 * Editorial register evolved from the app's design system: Fraunces serif,
 * warm paper canvas, near-black ink as primary, a single seal-crimson accent
 * for atmosphere. Dark-mode adaptive. One stylesheet shared by every page.
 *
 * Load-bearing files NOT touched by this rebuild:
 *   .well-known/apple-app-site-association  (Universal Links — must stay byte-stable)
 *   _headers, wrangler.toml, .assetsignore
 * The 404 page keeps its custom-scheme open-in-app fallback (re-skinned only).
