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.

DESIGN/10's ≥ 4.5:1 rule gets its owner. ContrastMath is the pure seam:
WCAG relative luminance (piecewise sRGB linearization), symmetric
contrast ratio, source-over compositing (an #RRGGBBAA board colour
resolves over the window background of the active appearance), and
inkChoice — native label if it clears AA, else the other appearance's,
else the higher ratio with meetsAA false (a mid-grey hex can max out
below 4.5 against both 85%-alpha labels; the app paints the best
available rather than overriding the user's colour). BoardTextInk is
the board's application: the decision is a ColorScheme, not a Color —
the text on the board fill is a hierarchy (.primary/.secondary/
.quaternary), and overriding the subtree's scheme moves the whole
vocabulary coherently. Recomputed on appearance change by construction
(read in body); label/backdrop colours resolve inside the asked-for
appearance, Increase Contrast variants included.
Two render sites — the only board text that sits on the user's colour:
the lane header (lanes draw no plate; title, icon, badge, rename field
and the + button land directly on the board fill) and the trash header
(its wash is ~5% effective alpha). Menus, popovers, and drag replicas
deliberately stay native; card faces carry their own opaque plates.
The card's premise fell during implementation: 03's "palette pairs
AA-verified at design time, pinned by a computed-contrast unit test"
was false — no such test existed, and the m4 path drew the native label,
failing AA in one appearance for all twelve wells (obsidian in Light
Mode: 1.0:1). Palette names now route through the same ink selection
(paintedColor delegates to Palette.nsColor — one predicate with
BoardView's paint decision), and PaletteContrastTests pins that the
chosen ink clears AA for every well in both appearances — plus
theNativeLabelIsNeverEnough, which would have failed on the m4 code.
Filed on the Redesign board for ratification. 1579 unit tests green,
both schemes build.
