The generator now reads three tracker columns instead of one and writes two
tables. Supported = In UI, Shape & Label Ok and Edit Handles all Y, which
tightens the old Shape-only rule and takes the count from 171 to 160. The
eleven that drop out are shape-verified but handle-unverified - exactly the
work this branch has been doing.

In UI = * is read as a wildcard: the column holds Y / N / blank, so taking it
literally would produce an empty table. Upcoming is therefore shape blank AND
handles blank, whatever In UI says - which is right anyway, since a graphic
not yet in the menu is still upcoming.

Thirteen rows now match neither table (shape done, handles pending, plus two
odd rows). The script prints that count rather than dropping them silently, so
widening the Upcoming filter stays a one-line decision.

gen-proven-graphics.py keeps the looser Shape-only rule on purpose - the
sample gallery is a picture of shapes, and a graphic with unfinished handles
still draws correctly. The hero caption now says so instead of claiming a
one-to-one match with the table.

Version 1.2.0: new drag behaviour across the edit handles, no breaking API
change. npm publish still has to be run from a real terminal - the 2FA here is
WebAuthn-only.
