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The owner's evening review superseded the same day's 4:5-ratio pass: 'reduce
vertical size of both pickers by 50%, on symbol picker by reducing padding.'
ComboFieldMetrics.height goes back to 1.4 em (18pt at the standard body,
exactly half the 4:5 pass's 36) — both combos get this for free, since it's
shared. width stops being height's own restatement (widthToHeightRatio is
gone); it holds the 4:5 pass's pixel figure as its own em number instead,
because re-deriving it at the new height would starve the trigger strip and
empty the face zone entirely.
SymbolComboControl.drawFace now sizes its glyph off the actual face rect it
is handed at draw time rather than the pure ComboFieldMetrics.glyphPointSize
(removed, along with its doc — it only ever described the control's intrinsic
portrait width, not the stretched-wide shape the card sidebar's row actually
proposes). No inset — SF Symbols carry their own margins — with the sizing
and overshoot-scaling rules split into two pure static functions so the fit
is assertable without a live draw.
ComboFieldMetricsTests updated for the new figures and the new actual-rect
glyph rule; the superseded 4:5-ratio-at-six-sizes test is replaced by one
pinning height/width independently and asserting faceWidth stays positive at
every size the old test used.

Owner's first review of the combo rework (2026-08-09): remove the face padding, make the
field taller and narrower at about a 4:5 width:height ratio, and center the symbol glyph in
its face. All three land in ComboFieldMetrics, so ColorComboControl and SymbolComboControl
stay the identical shape they were built to share.
- ComboFieldMetrics grows a width figure (height * widthToHeightRatio, 0.8), replacing
NSView.noIntrinsicMetric — every combo now carries its own taller, narrower intrinsic size
instead of stretching to whatever a caller's frame proposed.
- facePaddingH/facePaddingV/glyphPadding are gone; a face fills its zone edge to edge.
glyphPointSize is now whichever of the face's own width/height is smaller, with nothing
subtracted for padding that no longer exists.
- SymbolComboControl.drawFace centers the glyph on both axes — it only ever centered
vertically before, despite its own doc comment claiming otherwise.
- ComboFieldControl.drawTrigger bounds its chevron square by the smaller of the trigger
strip's own width/height, not height alone, since the strip is no longer close to square
once the field is much taller than it is wide.
- CardSidebarSections drops the sidebar's old '* 0.55' fixed-width frame on both combo rows;
each control now sizes itself, and both anchors (card sidebar, board popover) compose the
narrower field with no other changes needed.
- ComboFieldMetricsTests updated for the new figures, plus a ratio-holds-at-every-size test
and a rewritten glyph-fit test matching the no-padding rule.
Verification: xcodebuild build succeeded; xcodebuild test -only-testing:KanbanTests — 3220
tests in 559 suites, 3 failures, all PointerLatencyTests (documented locked-screen
environmental mode, confirmed unrelated by isolated rerun). Pixel verification unexercised —
same locked-screen constraint the first pass hit.

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.
