+### Visual regression (e2e)
+
+E2e tests use Playwright and compare full-page screenshots to committed snapshots. CI runs in `mcr.microsoft.com/playwright:v1.58.0-noble`; the **Linux** snapshot (`home-chromium-linux.png`) must be generated in that same environment or CI will fail (e.g. different height due to font/layout rendering).
+
+If CI fails with a snapshot mismatch (e.g. "Expected 1280×5985px, received 1280×5782px"):
+
+1. Regenerate the Linux snapshot in the CI Docker image:
+   ```bash
+   pnpm run test:e2e:update-snapshots
+   ```
+2. Commit the updated file(s) under `tests/visual.spec.ts-snapshots/`.
+
+Local `pnpm run test:e2e` uses the **Darwin** snapshot on macOS; the Linux snapshot is only used in CI.
+
 ### Option 4: Docker (Production-like Test)
 
 To test the production nginx image locally (same as deployed):
