/* ============================================================================
   51-label-picker.css - the label picker, the "new label" dialog and the colour
   swatch picker (Components/Shared/LabelPicker, CreateLabelDialog, ColorSwatchPicker).

   Sits after 50-datetime-field.css and before 24-theme-dark.css, which must stay last. Everything
   paints through the base tokens; the one [data-theme="dark"] rule below exists
   because the field mirrors .modal-search, whose dark face is a spot-fix in 24
   rather than a token, and the two must read as the same object.

   Three namespaces, no shared selectors with the rest of the cascade:
     .lp-*   the picker: field, chips, tray, list, foot
     .cld-*  the dialog
     .csp-*  the swatches

   The picker lives INSIDE the create modal and is quieter than it: no shadow of
   its own beyond --shadow-card, no motion, one violet (the open rim), and the
   list rows take the sanctioned borderless hover fill. The house hover rule
   (00-tokens-base.css) applies: the rim lifts, nothing moves. The swatches are
   the documented exception - a round target with no rim to lift scales instead.
   Mobile first: the base rules are the 375px layout.
