Variable CHROME_ICONSConst

CHROME_ICONS: Readonly<Record<string, string>> = ...

Path data for host chrome: the buttons around the chart rather than the tools in it. Same rules as the tool tier (one path per glyph, no presentation attributes, integer coordinates) on the 16 grid with a 1..15 live area.

The pair cursor / magnet / text also exist in the tool registry, at 24. They are drawn twice on purpose: a rail button and a toolbar button are different sizes, and the whole point of a second grid is not scaling one drawing to both.
