The two pickers rhyme — one two-zone chrome, a face onto a standalone browser, a trigger onto the popover

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.
