## Notes

- All component-specific CSS has been extracted into `.module.css` files
- All page-specific CSS has been extracted into `styles/pages/*.css` files
- Generic utilities (.stack, .row, .card, .button, .dialog, .form-field) remain in `styles/utilities.css`
- Shell layout and resets remain in `styles/global.css`
- Design tokens remain in `styles/tokens.css`
- Syntax highlighting remains in `styles/syntax-highlight.css`
- No visual regressions expected since all rules are preserved, just reorganized
