### Added
- Tier 1 class weapon-type proficiency check — a weapon type your class can never use
  (e.g. a one-handed sword on a Hunter) now correctly shows red/remove, even with an
  empty weapon slot. Previously this could show a false "upgrade," since the only
  prior weapon check (Option K, red tooltip text) only caught item-specific locks like
  Warglaives, not broad class exclusions. (Live-tested across 9 classes — Hunter,
  Shaman, Warlock, Monk, Druid, Demon Hunter, Priest, plus a regression check and an
  armor-type-downgrade check — with zero failures.)

### Known Limitations
- Spec-level exceptions not yet covered (e.g. Enhancement Shaman dual-wield vs.
  Elemental/Restoration) — planned as a future Tier 2.
- Not live-tested on Mage, Warrior, Paladin, Death Knight, or Rogue — table entries
  for those classes are sourced from the same documented reference data as the
  classes that passed, but unverified in-game.
