 # Design System
 
 All UI work — layout, color, typography, spacing, component selection, UX behavior — must follow [`docs/STYLEGUIDE.md`](./docs/STYLEGUIDE.md). Use the tokens defined in `src/renderer/src/assets/main.css` (the canonical source) and the shadcn primitives in `src/renderer/src/components/ui/`. Don't invent new color values, font sizes, or shadow tiers when a documented one already covers the role. When STYLEGUIDE.md is silent, follow the resolution order in its final section.
