- Reason: style 11 is landing-page oriented, mismatch for tool app
- Pick 10 BrandKit Purple (scene=app, Notion/Linear parallel)
- Light mode locked (long-form reading), dark mode reserved for v2
- Primary color: shift from BrandKit purple 310° to neutral blue-purple 275° oklch(0.58 0.18 275)
- Keep Inter + Noto Sans SC for mixed zh-en typography
- Rewrite all three page wireframes for light theme
- Inherit BrandKit's Surface layer system and large rounded corners
