wheel.half pins the centre to a screen edge and fans the items inward, for a
control that lives at the edge and has nowhere to open a full wheel. The arc
geometry is now shared with the full wheel, so the two cannot disagree about
which item a direction means. The hub is a glyph sized to the dead zone: the
cancel target you see is the one you hit.
list.rows takes a real control per row. A bare number printed beside the reorder
arrows reads as a stepper for that number, so moving a LoRA looked like editing
its weight.
setBusy re-derived disabled from the constructor's value, so finishing a busy
spell re-enabled a button that had been disabled since; busy and disabled are
tracked separately now.
An emptied number field committed as 0 and snapped to min, discarding the last
good value -- a browser normalises invalid text to empty, and Number('') is
finite so it sailed past the isFinite guard.
A context menu anchors to a POINT, and that stand-in reached the dismiss stack,
which threw on the first click anywhere.
