/* ============================================================
   FREE GAME UNIVERSE — constellation.css
   Concept: a vintage astronomical observatory catalogue.
   Constitution:
   - Two colours: space-ink #0b0e17  +  star-bone #ece6d6.
     One accent only: signal-amber #e8b23a (markers, active, coords).
   - Type: Fraunces (display serif) + Space Mono (coords/meta) + Hanken Grotesk (body).
   - Surfaces: 1px hairline rules, never card shadows. 5% grain.
   - Visible grid, catalogue designations (GM-0X), asymmetry.
   - Signature: filled diamond ◆ + mono designation before every record.
   Mobile-first; nothing overflows.
