-## [Unreleased]

-### Fixed
-- A tidy colour picker on CalDAV calendars. For calendars synced by a CalDAV
-  app (such as DAVx5), the event colour picker showed every colour the account
-  publishes — nearly 150 swatches in alphabetical order, many of them
-  duplicates or near-identical shades. The picker now shows only visually
-  distinct colours, arranged as a rainbow; near-duplicate shades and the
-  washed-out neutrals are folded away so no two swatches look alike. Picked
-  colours still sync exactly as before, and calendars with hand-picked
-  palettes (like Google's) are unaffected. Thanks to @ptab for the report
-  ([#22]).

- * hand-picked two-dozen set, while CalDAV adapters (DAVx5) dump all ~147 CSS3
- * named colours — including exact-value aliases (aqua/cyan, the gray/grey
- * spelling pairs) and dozens of visually indistinguishable whites and grays
- * (#22).
- *
- * Crucially, curation runs against the colour the picker actually *paints*, not
- * the raw provider value. The picker softens every swatch through [pastelArgb]:
- * it pins lightness to a constant and caps saturation, so the raw palette's
- * lightness axis is invisible on screen. Two raw colours that look different —
- * a navy and a mid blue — paint as one swatch, and every neutral (black, the
- * grays, white) paints as the same pale tint. Judging distinctness in raw
- * space, as before, left near-identical painted swatches and stranded the
- * neutrals as a run of look-alike "pinks" at the end of the grid.
- *
- * Three steps, all in painted space:
- *  1. Collapse swatches that paint identically to one (alphabetically-first key
- *     wins, deterministically) — this folds aliases, dark/light shades of a
- *     hue, and all the neutrals together.
- *  2. Oversized palettes (> [CURATION_TRIGGER_SIZE]) drop the washed-out
- *     neutral-origin tints (painted chroma < [PASTEL_CHROMA_FLOOR]) and are
- *     then thinned to visually distinct colours: most vivid first, a colour is
- *     kept only when at least [MIN_DELTA_E] (CIE76, painted Lab) from every
- *     colour already kept. Small palettes are already curated by their adapter
- *     and pass through whole.
- *  3. The survivors are ordered like a rainbow — continuously by painted hue —
- *     with the wheel cut at its single widest empty gap so the one unavoidable
- *     seam lands in dead space and no hue family is torn across both ends.
- *
- * Every surviving option keeps its provider [EventColorOption.key], so a pick
- * still round-trips through sync.
