   Display: Roboto Condensed (technical, instrument-panel feel)
   Body:    Source Serif 4 (readable, trustworthy, not generic)
   Mono:    JetBrains Mono (callsigns, version numbers, code)

   Why self-hosted: Google Fonts CDN transmits visitor IPs to Google, which
   conflicts with our privacy policy. Self-hosting also improves load
   performance and works on restricted/offline networks. See /fonts/README.md
   for download instructions and font version notes.

   All fonts are licensed under the SIL Open Font License (OFL).
   License files are included in the /fonts/ folder.
