components/ideas/idea-md-editor.tsx:
- Textarea-based editor with monospace styling for grill_md / plan_md
- kind='plan': live yaml-frontmatter validation as derived state via
useMemo (no setState-in-effect); inline errors with line numbers
- kind='grill': free markdown, no validation
- localStorage draft per (ideaId, kind) — lazy initial-value seeded on
mount; toast notice if drift from server
- Cmd/Ctrl+S keyboard shortcut to save
- Server-action 422 details surface as separate submitErrors state
components/ideas/idea-detail-layout.tsx:
- Grill/Plan tabs flip into edit-mode via "Bewerk" button when:
- grill: status in [GRILLED, PLAN_READY] (M12 grill-keuze 12)
- plan: status === PLAN_READY
- Empty-state offers "Schrijf zelf" when md is null + editable
- Demo always read-only
Tests: 546/546 still green.
