Subject: [PATCH 02/11] fix(markdown): download styled preview as pdf

- Replace print-window PDF export with html2canvas plus jsPDF direct save

- Capture the rendered markdown preview DOM so markdown-preview.css styling is preserved visually

- Paginate rendered canvases into A4 PDF pages

- Disable repeated PDF export clicks while rendering

- Add focused tests for canvas rendering, PDF pagination, and async preview export

Subject: [PATCH 03/11] fix(markdown): render pdf exports with printable layout

- Render markdown PDFs from an isolated A4-width clone instead of the live preview panel
- Add printable page margins and scale canvas slices to the PDF printable area
- Embed URL-based images as data URLs before html2canvas captures the export clone
- Strip unsupported lab/lch/oklch/color functions from export-only styles to avoid html2canvas parse failures
- Cover A4 sizing, image embedding, and color sanitization in markdown export tests

Subject: [PATCH 04/11] fix(markdown): sanitize html2canvas clone colors

- Add an html2canvas onclone hook for markdown PDF export
- Force cloned html and body backgrounds to safe RGB-compatible colors before parsing
- Re-run export subtree color sanitization inside the cloned document
- Cover clone document lab() background regression in markdown export tests

Subject: [PATCH 05/11] fix(test): stabilize jest markdown plugin mocks for ESM
 deps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- map rehype-katex, rehype-raw, remark-gfm, and remark-math to a shared Jest mock so Linux CI does not try to parse ESM-only packages from node_modules
- remove per-test inline plugin mocks now that the Jest config owns this compatibility layer
- rename __mocks__ files to kebab-case and update moduleNameMapper paths for naming consistency
- keep react-markdown test doubles focused on rendered content while centralizing plugin stubbing in one place

Verification:
- pnpm test ✅
- pnpm build ✅
- pnpm check ⚠️ fails on pre-existing Biome formatting drift in biome.json, app/chat/components/markdown-preview-panel.tsx, lib/markdown-export.ts, and lib/markdown-export.test.ts

Subject: [PATCH 06/11] feat(pdf): add server-side markdown export route

- add a Node.js route handler for markdown-to-pdf export
- add a Chromium-backed PDF service using puppeteer-core and @sparticuz/chromium-min
- render markdown, KaTeX, and Mermaid into print HTML before generating the PDF
- extend the Jest environment for route testing and document required export env vars

Verification:
- pnpm test -- lib/markdown-export/pdf-service.test.ts app/api/export/markdown/pdf/route.test.ts
- pnpm exec biome check lib/markdown-export/pdf-export-schema.ts lib/markdown-export/pdf-renderer.tsx lib/markdown-export/pdf-service.ts lib/markdown-export/pdf-service.test.ts app/api/export/markdown/pdf/route.ts app/api/export/markdown/pdf/route.test.ts jest.setup.ts

Subject: [PATCH 07/11] refactor(pdf): switch markdown preview export to server
 route

- replace the client pdf helper with a POST-based markdown export flow
- update the markdown preview panel to send source markdown instead of a live DOM node
- rewrite markdown export tests around API download behavior rather than html2canvas rendering

Verification:
- pnpm test -- lib/markdown-export.test.ts app/chat/components/markdown-preview-panel.test.tsx
- pnpm exec biome check --write lib/markdown-export.ts lib/markdown-export.test.ts app/chat/components/markdown-preview-panel.tsx app/chat/components/markdown-preview-panel.test.tsx

Subject: [PATCH 08/11] refactor(pdf): remove html2canvas export pipeline

- remove html2canvas and jspdf dependencies after switching markdown PDF export to the server route
- update the server renderer to use a runtime react-dom/server import so the Next.js route builds cleanly
- format biome.json so pnpm check passes again

Verification:
- pnpm test
- pnpm build
- pnpm check

Subject: [PATCH 09/11] refactor(pdf): make snapdom the only client export path

- collapse markdown pdf export onto the SnapDOM-based client pipeline
- remove the split server/snapdom export menu in the markdown preview panel
- update markdown export tests to target the SnapDOM PDF flow

Verification:
- pnpm test -- lib/markdown-export.test.ts app/chat/components/markdown-preview-panel.test.tsx
- pnpm exec biome check lib/markdown-export.ts lib/markdown-export.test.ts app/chat/components/markdown-preview-panel.tsx app/chat/components/markdown-preview-panel.test.tsx

Subject: [PATCH 10/11] refactor(pdf): delete server-side export implementation

- remove the markdown PDF route, renderer, schema, and Chromium service files
- drop puppeteer-core and @sparticuz/chromium-min after choosing SnapDOM as the only PDF path
- remove the server-export environment variables from .env.example

Verification:
- pnpm test
- pnpm build
- pnpm check

Subject: [PATCH 11/11] fix(test): remove undici polyfill from jest setup

- delete the undici-based Headers/Request/Response polyfill that was crashing in CI
- keep the stream, encoder, and worker polyfills that the test environment still needs
- replace the default fetch mock headers with a lightweight get() stub so tests stay decoupled from undici internals

Verification:
- pnpm test -- hooks/use-chat.test.ts lib/chat/workspace-hydration.test.ts app/chat/components/markdown-preview-panel.test.tsx
- pnpm test
- pnpm exec biome check jest.setup.ts
