"""Trigger detection patterns.

Triggers determine WHEN an ability activates:
- ON_PLAY: When member enters the stage
- ON_LIVE_START: When a live begins
- ON_LIVE_SUCCESS: When a live succeeds
- ACTIVATED: Manual activation
- CONSTANT: Always active
- etc.

Patterns are organized in tiers:
- Tier 1 (priority 10-19): Icon filenames (most reliable)
- Tier 2 (priority 20-29): Specific phrases
- Tier 3 (priority 30-39): Generic kanji keywords
