…terns (#630) ## Summary - Add a thin companion stylesheet export `@cfpb/design-system-react/dsr.css` for **Pattern B** apps that already load full Design System CSS and must not also load fat `index.css` (duplicate DS rules + fonts). - Expand the Pattern A `ds-components.ts` barrel so `index.css` covers more React-backed DS modules (list, button-group, expandables, search-input, hero, text-introduction, …). - Document Pattern A vs Pattern B clearly in the README (what to import, what not to combine). - Keep inactive Tabs on `isLink` / `a-btn--link` so dotted-underline link chrome stays correct while tab styles live in `tab.scss` / `dsr.css`. ## Why Existing CFPB apps already ship full `@cfpb/cfpb-design-system` CSS. They cannot safely import DSR `index.css` without duplicating buttons, forms, fonts, etc. Tabs (and other React-only overrides) live in DSR, not in the Design System package — so Pattern B had no clean CSS entry until `dsr.css`. ## What changed | Area | Change | | --- | --- | | `package.json` exports | Add `./dsr.css` → `dist/dsr.css` | | Build | Second Vite build (`vite.dsr-css.config.ts`) + cleanup stub script | | `dsr-styles.ts` | DSR-authored styles only (Tabs + React overrides); no fonts / no DS molecules | | `ds-components.ts` | Broader Pattern A coverage for `index.css` | | README | Pattern A / Pattern B / do-not-combine guidance | | Tabs | Restore `Button isLink` on inactive tabs for correct link styling | ## Consumer demos (`dsr-test`) | Demo | Shows | | --- | --- | | [dsr-test#7](cfpb/dsr-test#7) Pattern A | `index.css` only — Tabs OK | | [dsr-test#8](cfpb/dsr-test#8) Pattern B broken | Full DS CSS, **no** `dsr.css` — Tabs incomplete | | [dsr-test#6](cfpb/dsr-test#6) Pattern B fixed | Full DS CSS + `dsr.css` — Tabs fixed | Previews: - https://cfpb.github.io/dsr-test/pr-previews/pr-7/ - https://cfpb.github.io/dsr-test/pr-previews/pr-8/ - https://cfpb.github.io/dsr-test/pr-previews/pr-6/ ## Usage **Pattern A (new React apps):** ```ts import '@cfpb/design-system-react/index.css' ``` **Pattern B (existing DS apps):** ```ts import '@cfpb/design-system-react/dsr.css' // Do not also import '@cfpb/design-system-react/index.css' ``` ## Test plan - [ ] `yarn build` produces both `dist/index.css` and `dist/dsr.css` (no leftover `dsr-styles-entry.js`) - [ ] Storybook Tabs: inactive = dotted link; active = gray chip - [ ] Pattern A demo (#7): Tabs / buttons / slug look correct from `index.css` alone - [ ] Pattern B broken demo (#8): Buttons OK; Tabs missing DSR chrome - [ ] Pattern B fixed demo (#6): Tabs match Pattern A; no `index.css` import - [ ] Confirm README “do not combine” table matches the intended consumer guidance

Summary
Consumer demo for Pattern A against
design-system-reactrad-dsr-css-cleanup(DSR #630).Greenfield-style app: one stylesheet. Tabs, buttons, and slug heading should look correct without loading full Design System CSS.
