iconColor stops being hand-written-only (user-ruled, superseding 03's
"schema yes, control no"): it rides StyleCommand.apply → applyStyle as
the third styled dimension — per-dimension no-op skip, one bracket, one
history step, ExpectedField.iconColor for staleness. The SymbolPicker
grows an opt-in colour row (leading None plus seven Palette.foregrounds
hues, None removes the key); the board popover is its one caller. The
window-title widget now draws the board's resolved glyph in that tint
beside the name. Doc realignment filed on the Redesign board (Minor).
