Summary

When Plotium cannot find a system UI font, the Phosphor icon font can make lowercase letters and hyphens disappear. Use the bundled text font before Phosphor, keep system semibold headings when available, and retain regular faces to cover missing glyphs. Document the bundled English fonts in both installation guides.

Validation

  • On Ubuntu 22.04, compared both builds with an empty system font list. Lowercase text and hyphens became readable, and icons still rendered.
  • cargo pr-check passed, including regression tests for printable ASCII, icons, and heading font fallback.
  • npm run build passed in docs/.
