Implements MVP2 of the ElementConfigs system, applying default styles to newly created nodes.
✅ Completed:
- ElementConfigRegistry with singleton pattern
- 5 node configs (Button, Text, Group, TextInput, Image)
- 28 total style variants defined
- Integration in router.tsx for app startup
- Unit tests for registry
✅ Validated:
- Button node: 100% defaults applied correctly
- Text node: Partial defaults applied (fontSize, color work)
- System initializes successfully at startup
⚠️ Known Issues:
- Text lineHeight and fontWeight not fully applied (likely interaction with legacy text style system)
- Requires cache clear (npm run clean:all) for changes to take effect
📝 Documentation:
- MVP2 validation report with test results
- Detailed changelog of implementation steps
🚀 Next: MVP3 will add variant selector UI in Property Panel
Ref: STYLE-002 Phase 9
- Add GroupConfig with 7 variants (default, card, section, inset, flex-row, flex-col, centered)
- Add TextInputConfig with 2 variants (default, error) and 4 states
- Add ImageConfig with 3 variants (default, rounded, circle)
- Register all 5 configs in initElementConfigs()
- Node creation hook already implemented in NodeGraphNode constructor
- Total: 5 configs with 28 variants across all elements
- All configs use design tokens for theming
MVP 2 Status: ✅ Complete (ready for integration testing)
- Implemented StyleTokensModel for managing design tokens
- Added StyleTokensInjector to inject tokens into viewer preview
- 10 essential default tokens (primary, background, foreground, border, spacing, radius, shadows)
- Token storage in project metadata (styleTokens field)
- Real-time CSS variable injection in preview
- Fixed bug: tokens now inject for legacy projects without styleTokens field
- Tested and validated (see TEST-REPORT.md)
MVP does NOT include:
- UI panel for editing tokens
- Token picker component
- Import/export functionality
- Full token set (only 10 essentials)
These features are planned for STYLE-001 Full implementation.
