⌥-drag does not survive the trip. Most Linux window managers grab Alt-drag to
move the window, so the page never sees the pointer and the gesture is simply
absent — on the machine it is absent from, with no error and nothing to find.
Reported from one.
⌃ (⌘ on a Mac) now places the pivot, which is the modifier the rest of this
stage already reaches for. ⌥ keeps working for anyone whose desktop leaves it
alone; ⇧ is deliberately not it, since it means CONSTRAIN everywhere else here —
uniform scale, 15° turn steps — and is what a snap to the child's corners will
want when this drag grows one.
The menu row says so, because a modifier nothing mentions is a modifier nobody
finds: "add peg · ⌃/⌘-drag its cross to place the pivot".
`peg.mjs` now asserts each modifier through real pointer events instead of
reading the handler, which is the only way this class of bug shows up — all
three place the pivot with a child drift of 0, and an unmodified drag still
translates.
