/* ==========================================================================
   Momentum — styles
   Palette adapted from the Notion design system (warm ground, one purple
   action accent, pastel status tints). The three lane colours (blue / amber
   / green) are a deliberate documented exception to the single-accent rule:
   each colour encodes a workflow state, the way Notion's database properties
   and Linear's issue labels do. Purple stays the ONLY interactive accent.

   ponytail: the dark palette is duplicated across two selectors below
   (system preference + explicit toggle) because there is no build step to
   dry it up. It is a list of colour values, not logic.
