WebMux self-hosted fonts

Inter (Latin UI) — SIL Open Font License 1.1. See OFL-Inter.txt.
Maple Mono NF CN v7.9 (terminal, code and Nerd Font icons) — SIL Open Font
License 1.1. See OFL-MapleMono.txt. CJK glyphs and ligature features are
removed; CJK text uses system sans-serif fonts.

HarmonyOS Sans SC is not included. Its license forbids modifications, which
rules out the unicode-range slices this app serves, and it does not allow
redistributing the font files on their own.
