  /* ── Emerald palette (V39.57 redesign) ───────────────────────────────
     The app was originally navy/teal. To recolour everything in one place
     we keep the original variable NAMES but point them at Emerald values,
     so every existing rule that uses --navy/--teal picks up the new scheme.
     --navy  → emerald ink (dark text / primary)
     --teal  → emerald brand (accent / actions) */
