 * Bundled webfonts. Chromium shapes text with HarfBuzz on every OS, so a font served with the app
 * measures identically everywhere, while a system font (Segoe UI on Windows, whatever fontconfig
 * picks on Linux) does not — and differing advance widths re-wrap prose, which moves the height of
 * a full-page screenshot. Shipping the faces is what lets ScreenSnapshotTests compare PNGs on any
 * OS. See wwwroot/fonts/readme.md for provenance and licences.
 *
 * The unicode-range descriptors are the source of truth for what the bundled subsets cover:
 * RepoContractTests.ShippedFontsCoverRenderedText parses them and fails if the wizard renders a
 * character that would fall through to a system font.
