Fonts vendored into VernierCAD
==============================

All four faces are licensed under the SIL Open Font License, Version 1.1,
which permits bundling them with (and inside) a software binary. They are
vendored rather than fetched because a CAD application must not render
differently offline — see the note in `src/theme.rs::install_fonts`.

    Used only for glance-length chrome: tabs, group captions, section
    headings, mode pills. Never a paragraph.

    The value voice: command labels, dimensions, paths, ids, status.

  IBMPlexSans-Regular.ttf
    IBM Plex Sans, Copyright 2018 IBM Corp. Version 3.2. SIL OFL 1.1.

    Sentences: explanatory lines, refusal copy.

    Fallback behind IBM Plex Mono in the Monospace family, for the
    mathematical-operator glyphs a constraint tile's own icon literal uses
    (∥ U+2225, ⊥ U+22A5, ⌒ U+2312) that no other vendored or egui-bundled
    font covers — card a702a313. Chosen over drawing icons for these
    symbols because `icons.rs`'s own standing decision rules that out:
    constraint symbols use the notation a CAD user already reads, not a
    commissioned glyph.
