+## Source Files
+
+The `rumraisin/src/` directory contains design sources in proprietary VFB format only, which cannot be built with gftools-builder:
+
+- **VFB** (FontLab, proprietary format, not buildable with gftools): RumRaisin-Regular-OTF.vfb, RumRaisin-Regular-TTF.vfb, RumRaisin-Regular.vfb
+- **OTF** (compiled binaries, not design sources): RumRaisin-Regular.otf

+## Buildability

+Not buildable with gftools-builder. The VFB sources are in FontLab's proprietary format. Conversion to UFO or Glyphs format would be required before a reproducible build pipeline could be established.
