Both the symbol picker and the background color control give up the two-zone combo chrome from the 2026-08-09 rework: no more face/trigger split, no more trailing chevron square. Each is now a single bordered rectangle with one hit zone, 2.1em tall and 1.5x that wide (a 4:6 ratio, 50% taller than the retired chrome's 18pt). A click anywhere opens the same curated popover the trigger used to gate.
The background rectangle's popover is new: a None-plus-sixteen palette grid mirroring the Style… popover's own wells, with an Other… row onto the shared, pre-debounced Colors panel session — replacing the old NSMenu dropdown outright. The symbol rectangle keeps its existing popover (search, curated grid, tint colors, More Symbols…) verbatim; only its entry point collapsed to one zone.
ComboFieldControl/ComboFieldMetrics (ComboField.swift) are replaced by PickerRectControl/PickerRectMetrics (PickerRect.swift). ColorComboView and its NSMenu-building pure model are retired wholesale in favor of ColorSwatchPicker. SymbolComboControl becomes SymbolGlyphControl. PaletteSwatch.rectImage, the last caller of which was the retired dropdown's menu rows, goes with it.
In the card window sidebar, the "Style" section header becomes "Appearance" (sidebar only — the board context menu's Style… item and StyleEditorView's own naming are untouched), and the symbol and background controls move from stacked rows to side-by-side columns, each captioned above rather than leading. CardStyleSection no longer carries its own debounce Task for background panel picks — the shared Colors-panel session now delivers an already-settled value.

The colour combo was a wide two-zone field with a second door onto the Colors
panel; the symbol picker was a small square button with one. Both now subclass
one `ComboFieldControl`, so they are the same width, height, radius and trigger
by construction: click the face for the standalone picker, click the chevron for
the quick list. The symbol face opens a new floating browser over the OS's own
category, ordering and keyword plists out of CoreGlyphs.bundle — searchable,
categorised, trademark-restricted glyphs withheld.
The palette grows twelve to sixteen per table, filling the hue ring's four
widest gaps with lime, jade, indigo and magenta at each table's own saturation
and brightness. That gives the Style… popover's background grid a third row and
the tint grid its third row of four, and both grids gain an Other… row onto the
system colour picker — which the card sidebar's combo has had all along and the
primary styling surface never did. An arbitrary hex already round-tripped; it is
asserted now, including that an unquoted one is a YAML comment and no value.
