# Playwright + headless Chromium

Installed **box-wide on nh3-dev**. Use for anything needing a real browser engine:
true DOM/SVG layout geometry, screenshots, headless rendering, browser-based tests or
scraping.

- System shared-libs installed via apt (`playwright install-deps`)
- Browser binaries in shared **`/opt/ms-playwright`** (root-owned, world-readable)
- `PLAYWRIGHT_BROWSERS_PATH=/opt/ms-playwright` wired globally
  (`/etc/environment` + `/etc/profile.d/`)

A project needs only the `playwright` module — `npm i playwright`. **The browser
download is skippable and there is no per-project `playwright install`**; it resolves
the shared binary.

Add a browser or bump versions:

```sh
ssh infra-ops@10.100.10.50 \
  'sudo env PLAYWRIGHT_BROWSERS_PATH=/opt/ms-playwright npx -y playwright install <browser>'
```
