Marks now support parametric values via colon syntax:
- color:#hex — foreground text color
- bgcolor:#hex — highlight / background color
Existing boolean marks (bold/italic/underline/strike/code) are
unchanged. Empty value (color:, bgcolor:) clears that slot.
Engine
- WordsMark union extended with `color:\${string}` and
`bgcolor:\${string}` template literal variants.
- isWordsMark accepts the parametric form (validates against #hex
3/4/6/8 digits).
- normalizeMarks de-duplicates by prefix for parametric marks (only
one color, one bgcolor per inline survives).
- toggleMarkSet REPLACES same-prefix entries instead of toggling
them; empty value strips the slot.
- New helpers markValue() and markPrefix() for reading parametric
data.
Serializers
- HTML out: wrapMarks collects color/bgcolor into a single
`<span style="color:..;background-color:..">` instead of nested
spans, then wraps with the boolean-mark tags.
- HTML in: not extended this pass — round-trip via style attr is a
follow-up. The marks survive in the document model + render OK.
- Markdown out: silently drops parametric marks (no MD syntax for
inline color; HTML round-trip is the supported path).
DOM render
- createWordsTextAttrs splits marks into booleans (→
data-words-marks) and parametrics (→ inline `style` attr) so the
contenteditable paints the colors directly.
Drawer Format panel
- New "Foreground" + "Background" sections with:
- 10-swatch palette (red/orange/amber/green/cyan/blue/violet/pink/
white/grey) — hand-picked editorial set
- Native <input type=color> for free hex pick (no preset constraint)
- "×" clear button (only when a value is set for that slot)
- Active swatch outline when the current value matches the preset
- runCommand passes the `color:#hex` / `bgcolor:#hex` string straight
through commandFromName → toggleMark.
WordsCommandName extended with `color:\${string}` and
`bgcolor:\${string}` for type-safe consumer calls.
152/152 tests pass. Verified visually: clicking the red swatch on
selected "ActiveUI" text in the demo produces
`<span data-words-marks="bold" style="color:#ef4444">ActiveUI</span>`
in the rendered HTML, text paints red in the editor, the swatch
shows active outline + clear (×) button appears.
