New grammar panel replaces free-text AI prompt with a two-step workflow:
1. NL to Grammar: GPT-4o converts description to patch ops (new endpoint ai-to-grammar)
2. Apply: frontend parser applies grammar locally without AI
Grammar syntax: (+|-|~)(node|edge|coef|input|instruments) key=val key=val
Sign shortcuts: + positive, - negative, = neutral
Auto-positions new nodes when x/y omitted.

Library:
- Color chip filters: category (with per-category colors), sub_type, instrument
- Date range filter (created_at) + text search
- Category labels unified to cover event_calendar, fundamental, calendar_event etc.
- Editer button on selected template → opens in editor tab
- Show created_at + created_by in template detail
Editor:
- Accepts initialId prop so Library can pre-load a template
- AI Modify zone: textarea prompt + button calls /api/causal-lab/template/{id}/ai-modify
- Returns modified graph_json from GPT-4o, applied live — user reviews then saves
Backend:
- New POST /api/causal-lab/template/{id}/ai-modify endpoint
- Sends current graph_json + user prompt to GPT-4o
- Returns validated modified graph_json (nodes/edges required)
- Does not auto-save (user controls save)
