-## Canonical Upstream Repository
+## Build Configuration (Override)
-The canonical upstream repository is **vernnobile/oxygenFont**: https://github.com/vernnobile/oxygenFont
-
-This is the designer's own repository. The README describes the Oxygen Font as "originally aimed as a desktop/gui font for integrated use with the KDE desktop." The repository contains:
-
-- `Oxygen-GoogleWebFont/src/` — SFD source files for the Google Fonts (web font) version:
- - `Oxygen-Regular.sfd`, `Oxygen-Light.sfd`, `Oxygen-Bold.sfd`
-- `Oxygen-Monospace/src/` — SFD and UFO sources for the monospace variant (see OxygenMono report)
-- `OxygenSans-version-0.2/` and `OxygenSans-version-0.4/` — older milestone versions

-## Source File Analysis
-
-The Oxygen Sans sources in this repository use FontForge SFD format only. No UFO or Glyphs source files exist for the Oxygen Sans weights. The designer subsequently renamed the Oxygen font family to "Comme" (https://github.com/vernnobile/commeFont), which contains full UFO sources, but that is a separate evolution of the design.
-
-## Conclusion
-
-The canonical designer-owned upstream repository is `vernnobile/oxygenFont` at https://github.com/vernnobile/oxygenFont. However, since the Oxygen Sans sources exist only in SFD format (no UFO or Glyphs), no source block was added to METADATA.pb. The newer "Comme" continuation of this design (https://github.com/vernnobile/commeFont) contains UFO sources but represents a different, expanded family.

+An override `config.yaml` has been created in the google/fonts family directory, referencing `Oxygen-Regular.ufo` from `vernnobile/oxygenFont`. This is a best-effort starting point for reproducible builds — the shipped binary was likely built with different tool versions and may not match exactly.
