The controls whose chrome was hardcoded dark now adapt to a light base —
previously they rendered as dark chips/holes on light themes. (Flat knobs and
faders already adapted: their face is the `face` token.)
- `ledWell` theme token — the recessed screen behind LED segments (LEDKnob,
LEDFader, Meter) and the default well of SegmentDisplay / AlphaDisplay now
comes from the theme. Dark base keeps #0b0d0e; light base is `transparent`,
so LED controls and readouts render as clean flat rings / bars / digits on
the light panel. faceColor / background props still override.
- `scheme` theme token ('dark' | 'light', set by base) + a shared
panelButtonChrome() helper drive the raised gradient/border/shadow of
PushButton (and Button), TransportButton and SegmentSwitch — light raised
buttons on light themes instead of dark chips; unlit LED pips flip to a
faint dark so they still read.
- Docs: a "Light theme" gallery card showing the panel family under
base="light"; ledWell/scheme documented; install URLs bumped to v1.1.4.
Library + docs typecheck and build; 46 tests pass.
