Window > Swatch Libraries and the Swatches panel's library button open a
read-only, floating library panel (thumbnail and list views, find field,
libraries menu, previous/next arrows). Clicking a swatch adds it to the
document and applies it as one undo step; Shift/Cmd-clicks select swatches
and groups for Add to Swatches. Default Swatches restores missing defaults.
Libraries are computed in code (OKLCH, rounded to 8-bit sRGB): Web Safe 216,
Grays and Neutrals, Earth Tones, Skin Tone Ramps, Pastels, Brights,
Metallic Gradients, Perceptual Scales, Harmony Sets.
Commands: swatch.library.list, swatch.library.get, swatch.library.add
{library, names?, apply?, focus?}, swatch.resetDefaults {replace?};
UI command window.swatchLibrary {library}.
