The Colors panel joins the palette — the combo ratified, and each anchor composes the halves it needs

Four rulings close Redesign Contradiction 3452893f (2026-08-06): the in-app
escape hatch is ratified in full, reversing 2026-07-29's palette-only rule —
the combo's Other… opens the system Colors panel, a pick landing on a palette
color stores the name, anything else the hex. Free-picked colors change no
contrast story: they land on the same runtime ink computation hand-written hex
always got (10 amended to say so; no warning surface is owed). Anchor
ownership: the card sidebar's background story is the combo alone — the well
grid's background half stays with the other anchors (StyleEditorView gains
showsBackground beside showsSymbols; the popover's symbol half already went to
its inline SymbolPicker). Quick-style recents stay palette-vocabulary — a
panel pick never enters them.
