bflatasticandClaude Opus 5.5 bfebf66404 M3.53: Color Guide has 21 harmony rules, Steps and Variation options, a fixed base colour and Save Colors as Swatches
The harmony rules (Complementary 1/2, Split Complementary, Left/Right Complement, Analogous 1/2,
Monochromatic, Shades, Triad 1-3, Tetrad 1-3, Compound 1/2, High Contrast 1-3, Pentagram) live in
the color crate with our own math, base colour first. The variation grid moves there too
(`harmony::Guide`): a row per harmony colour with the colour in the centre column, shades/cool/muted
to the left and tints/warm/vivid to the right, 1-20 steps and a variation amount.

- `color.harmony {color, rule, steps?, variation?, amount?}` query returns {rule, colors, grid}.
- The panel keeps its base colour until "Set base color" takes the current one; Shift/Cmd-click
  selects several cells and Save Colors as Swatches saves them (`swatch.new {colors}`, one step).
- Color Guide Options dialog (`ui.colorGuideOptions`, kind `colorGuideOptions`) with a preview row;
  the options persist in `UiState::color_guide`.
