Detailed Description

WYSIWYG text-edit metrics — the geometry an inspector edit overlay needs to draw a caret + selection band that EXACTLY matches the glyphs paint() renders.

The label's painter resolves inherited size/weight/letter-spacing, family fallback, slant, text-transform, and an alignment-dependent draw origin; an overlay that re-measures with the Label's OWN fields drifts whenever any of those differ (e.g. a PARENT sets letter-spacing, or the label is center/right aligned). This factors the same style/origin resolution paint() uses so the two can never disagree.

caret_x_by_byte[i] is the caret x (local, measured from local_text_left) for the byte boundary at index i over the supplied edit_text — the buffer the overlay is currently editing, NOT text() (which is mid-edit). It has edit_text.size() + 1 entries (one per boundary, including end-of-text).
