+Task: Implement Attunement System (Major Feature)
+
+Work Log:
+
+**Phase 1: Core System Design**
+- Designed 7 body slots: rightHand, leftHand, head, back, chest, leftLeg, rightLeg
+- Created 7 attunement types with unique capabilities:
+  - Enchanter (rightHand): Transference mana, enchanting unlocked
+  - Caster (leftHand): Form mana, +25% spell damage
+  - Seer (head): Vision mana, +20% crit, reveal weaknesses
+  - Warden (back): Barrier mana, -10% damage taken, shields
+  - Invoker (chest): Guardian pact mana types, pact abilities
+  - Strider (leftLeg): Flow mana, +15% attack speed
+  - Anchor (rightLeg): Stability mana, +100 max mana
+
+**Phase 2: Type System**
+- Created attunements.ts with:
+  - AttunementSlot, AttunementType, ManaType types
+  - AttunementDef interface with skills, mana types, regen bonuses
+  - ATTUNEMENTS constant with all 7 attunements defined
+  - Each attunement has 4 attunement-specific skills
+- Updated types.ts:
+  - Added attunement imports and re-exports
+  - Added attunement fields to GameState
+  - Updated SkillDef to include attunement field
+
+**Phase 3: State Initialization**
+- Updated store.ts makeInitial():
+  - Player starts with Enchanter attunement unlocked
+  - Initialize all 7 attunement slots
+  - Initialize primaryMana pools (start with 10 transference)
+  - Initialize primaryManaMax (50 per type)
+
+**Phase 4: Mana Conversion**
+- Implemented auto-conversion in tick():
+  - Each attunement converts raw mana to its primary type
+  - Conversion rate = autoConvertRate × (1 + level × 0.1)
+  - Conversion costs 1 raw mana per 1 primary mana
+- Updated starting message to reflect attunement theme
+
+**Remaining Work:**
+1. Update enchanting system to use transference mana
+2. Create UI for attunement display
+3. Add attunement earning challenges (placeholder)
+4. Migrate existing skills to attunement-specific categories
+5. Update skill evolution for attunement skills
+
+Stage Summary:
+- Core attunement system architecture complete
+- Player starts with Enchanter attunement
+- Auto-conversion of raw to primary mana working
+- All lint checks pass
