/*
 * Éclore Aesthetics — 404 (Not Found) page
 * ─────────────────────────────────────────────────────────────────────────────
 * Editorial composition on the warm ground: an oversized, faint "404" ghost
 * numeral sits behind a serif-accented headline, a short body line, and a
 * recovery link set — one primary Terracotta pill (the single accent, used once)
 * followed by three spaced secondary text-links. Generous vertical rhythm so the
 * page reads as intentional. The compound focus ring on every link is owned by
 * global.css (§8).
