This runtime uses MiSans fonts by Xiaomi.
Official source: https://hyperos.mi.com/font/zh/download/
Archive: https://hyperos.mi.com/font-download/MiSans.zip
Download mirror (third-party, not an official Xiaomi repository):
https://github.com/boyan01/mi_sans_font/tree/68f3ec3fee5830ce8a1d955d462fa0df401a5341/lib/fonts
Files: MiSans-Regular.ttf and MiSans-Bold.ttf
These mirrored files differ from the current official ZIP; they are not claimed
to be the latest release. The mirror repository's license does not replace the
Xiaomi font license.
MiSans is subject to the MiSans Fonts Intellectual Property License Agreement
published on the official download page. It is not an open-source font license.
