/* =============================================================
   ArcadeLab — Stylesheet
   Phase 02: Design System + Premium Home Experience
   (Phase 01 established the token baseline; this phase formalizes
   and extends it — see .claude/PROJECT-CONTEXT.md §5 for the full
   documented system and .claude/DECISIONS.md for rationale.)

   Design concept: arcade-cabinet materiality rather than generic
   "dark SaaS" styling — a warm, near-black cabinet body with
   backlit marquee-glow accent colors. Each game gets one identity
   color (gold / cyan / rose), used ONLY for that game's own
   elements — never repurposed as decoration elsewhere, so the
   color-coding keeps a consistent meaning across the site. Gold
   doubles as the studio's primary brand accent.

   Breakpoint scale (documented here since plain CSS media queries
   can't reference custom properties without a build step):
     640px  – container gutter increases
     800px  – about-grid / philosophy-grid become multi-column
     900px  – desktop nav appears + hero becomes two-column
   ============================================================= */

   The "sample entry" badge deliberately borrows --color-rose, which
   section 1 reserves for per-game identity — a documented, narrow
   exception: this badge exists specifically so a placeholder entry
   can never be mistaken for a real announcement, and visibility wins
   over palette discipline for that one job. It only ever appears on
   the placeholder entries in updates/data.php, not on genuine ones —
   see .claude/DECISIONS.md.
