Provenance
Files in this directory were obtained from the upstream release artifacts
linked above on 2026-05-03. Source Serif 4 woff2 files were generated locally
from the desktop OTF release using fonttools ttLib.woff2 compress; all
others are unmodified from upstream webfont releases.
Why bundled
These fonts ship with the design system to eliminate runtime requests to external CDNs (e.g., fonts.googleapis.com). This guarantees:
- No data leakage about end-user IPs / User-Agents to third parties.
- GDPR compliance for Norwegian public-sector deployments.
- Functioning Playgrounds in offline / air-gapped environments.
Each Playground HTML loads ../shared/playground-design-system/fonts.css,
which declares all @font-face rules pointing at the .woff2 files in this
directory.
