/* The Halal Scout — the single CSS file (tech spec §6, §17.5).
   Layer order: 1 tokens → 2 reset/base → 3 components → 4 utilities.
   RULE (§16.11): components reference tokens ONLY — no hardcoded hex/px in component rules.
   Contrast note (§16.2): every pairing is intended-AA, verified before launch (G5 checklist);
   --color-ink-muted is BELOW 4.5:1 on --color-bg — never use it for small text (use
   --color-ink-secondary); reserve muted for large/non-essential text. */
