- Add ITEM_RARITY (common/uncommon/rare/legendary) with per-item tier caps - Weighted pools per source: elites favour common, item rooms uncommon, bosses rare/legendary; legendaries are boss-exclusive; capped items excluded - Rarity-weighted powerScore so deep common stacks inflate difficulty less - Differentiate duplicates: Grafted Trigger, Crow Bait, Hollow Bones, Twin Hearts - 14 new clean passives incl. Chill Gland (activates slowOnHit) and Hooked Sinew (activates magnetPull); revive magnetPull in pickups - Rarity-tinted pedestal glow + nameplates, rarity-sorted HUD implant tray, dynamic help implant pages (8 -> 9) - Generate 14 item icons via gen_assets.py; bump asset cache to v=38 - Update smoke tests for 60 items, per-item caps, pools, weighted power
