Document symbols placed inline in a run of type (beyond Illustrator; like InDesign inline anchored objects): TextRun.inline holds the symbol, scale and shift; the run is one U+FFFC laid out as a glyph sized to the art, centred on the cap height. text.insertInline and Type > Insert Inline Symbol; editing keeps the graphic whole; canvas, SVG (<use>) and PDF draw the art; Create Outlines turns it into a symbol instance.

//! Strokes on type in SVG: character stroke options on live text (and back), runs that differ
|
||
//! from the first, and the object's own strokes drawn over the glyph outlines.
|

// Integration tests: unwrapping and panicking on failure is fine here, unlike in shipped code (AGENTS.md › Robustness).
