# E2E visual artifacts (#65)

Screenshots from `npx playwright test` for Milestone 2 Photos-ready evidence.

## How to run (local box — not ubudual :10880)

```bash
cd frontend
npm ci
npx playwright install chromium   # once per machine
npm run test:e2e
```

Or against an already-running preview:

```bash
npm run build && npm run preview -- --host 127.0.0.1 --port 4173
# other terminal:
npx playwright test
```

Fixtures: `tests/fixtures/set1-48x2/` (L=48, thickness=2) and `set2-31x2p5/` (L=31, thickness=2.5). Black sheet — e2e selects **Black** and may nudge sensitivity.

## Expected screenshots (this folder)

| File | Step |
|---|---|
| `01-batch.png` | Batch with fixtures loaded |
| `02-pick-calibration.png` | Pick calibration |
| `03-mask.png` | Mask (Black sheet) ready to approve |
| `04-axis.png` | Length axis |
| `05-measure.png` | Measure with L / thickness filled |
| `06-photos-ready.png` | Photos ready lineup (clean + overlay + siblings) |

Large regenerating `*.png` and Playwright `test-results/` / `playwright-report/` are gitignored.
Committed small evidence JPEGs live in `evidence/` (regenerate with a green `npm run test:e2e`, then re-encode if needed).

## Unit tests

`npm test` must still pass separately from Playwright.
