## Commands

No Makefile or npm scripts. Available commands:

- `composer install` — install dependencies (requires [composer-agent-skill-plugin](https://github.com/netresearch/composer-agent-skill-plugin))
- `node skills/netresearch-branding/scripts/contrast-audit.cjs <page>` — measure a rendered page against WCAG AA in headless Chromium (needs `playwright-core`: `npm ci --ignore-scripts` installs the version `package-lock.json` pins (declared in `package.json` under `optionalDependencies`; `--ignore-scripts` keeps the peer dependency's postinstall from rewriting this file), `npx playwright-core install chromium` its browser; or set `PLAYWRIGHT_CORE` to another install). Exits non-zero on a text-contrast failure, a focus indicator or form-control boundary below 3:1 (SC 1.4.11), or a stylesheet/script that did not load. `.github/workflows/contrast-audit.yml` runs it against `skills/netresearch-branding/templates/landing-page.html`, `examples/components.html` and `site/index.html` on every change to those paths, so a colour regression fails CI rather than shipping.
- `uv run Build/Scripts/check-brand-colours.py` — fails when a tracked CSS, SCSS, SVG, HTML, Markdown, JSON or YAML file uses a near miss of a brand colour: not equal to `#2F99A4`, `#585961` or `#FF4D00`, but every RGB channel within 8 of one, or CIEDE2000 below 2. The script header lists what it reads, what it does not, and the deliberate quotes. Tests: `uv run --no-project --with-requirements Build/Scripts/check-brand-colours.py python -B Build/Scripts/tests/test_check_brand_colours.py`. `.github/workflows/brand-colours.yml` runs both.
- `uv run Build/Scripts/tests/test_hosted_manual_checkpoints.py` — exercises NB-17/18/19 against hosted TYPO3 and standalone HTML fixtures; the same command runs in the pre-commit hook and Page Branding Profiles workflow.

## Rules

1. **Colors**: Primary `#2F99A4` (turquoise), accent `#FF4D00` (orange — accent only), text `#585961`
2. **Typography**: Standalone pages use Raleway for headlines and Open Sans for body; hosted TYPO3 manuals retain the official TYPO3 theme fonts. Calibri applies to office documents.
3. **Logo**: Standalone pages use `skills/netresearch-branding/assets/logos/netresearch-symbol-only.svg`, min 32x32px icon / 120px digital. Hosted TYPO3 manuals retain TYPO3's header and use the content branding profile below.
4. **Footer**: Must link to https://www.netresearch.de/ with "Netresearch DTT GmbH"
5. **Accessibility**: WCAG AA compliance mandatory
6. **White space**: High white space design principle throughout
7. **TYPO3 extensions**: Icon at `Resources/Public/Icons/Extension.svg`, vendor `netresearch/`
