All previews use only the bundled font — no fallback stack. Verification checks the font file and confirms the browser is rendering from it (no swap). Serve locally: python3 -m http.server 8000 · Live: notosans-glyph-test.pages.dev

Definitive proof pixel test

NotoSans can look similar to your system Japanese font — that is normal. This test compares pixel data, not appearance. If the browser matches the .ttf file and differs from the system font, it is definitively using the bundled font.
