The family a diagram glyph is drawn in. Repointed to the user’s selected
font when the fonts are installed, so switching fonts restyles the drawing
and leaves the UI chrome alone.
Iosevka (“Monospace”), embedded at compile time — SUBSET, not the full
face. The full build is 10.8 MB of mostly full-Unicode glyphs and twenty
stylistic sets the shaper never enables; this 222 KB subset keeps Latin,
Greek (for Ω/µ-grade labels), punctuation, sub/superscripts, currency,
letterlike, arrows, math operators, box drawing, blocks and geometric
shapes, with hinting and the default layout features. A label using a
character outside those ranges falls back per the host’s family list. To
