	Marker on a source-reference chip that carries no match count - the chip a focus-reference rope hangs off. A small lozenge reads as "this is the styling this rope points at" without competing with the numeric chips beside it.

Detailed Description

Non-ASCII glyphs the editor chrome draws as text, in one place.

ImGui only rasterizes the codepoints a font is asked for, and only those the font actually has: a codepoint outside the embedded fonts' cmap is silently dropped from the atlas and drawn as the font's fallback character, a literal ?. Keeping the glyphs and the atlas ranges next to each other lets one test assert the whole set is really present in the fonts the editor ships.

Initial value:

= {

    kSourceReferenceChipCodepoint,
}

Every non-ASCII codepoint the editor chrome draws, ascending. Both the font atlas ranges and the embedded-font coverage test are built from this.
