SynthEdit ships these rather than asking the OS for a font family, because the
same family name resolves to a different face on each platform - "Verdana" is
Verdana on Windows and Noto Sans on a typical Linux box. The advance widths
differ, so text extents differ, so a module box auto-fitted to its pin labels
comes out a different width per platform. Bundling the face makes layout
identical everywhere and lets the D2D golden images mean something off Windows.

Selawik covers Latin only (~348 codepoints: ASCII, Latin-1, most of Latin
Extended-A). Anything else - Cyrillic, Greek, CJK - is left to the text engine's
per-codepoint fallback, which reaches the system font database. That is why
`findBundledFont` declines requests carrying `mustCoverCodepoint`.
