/* ---------------------------------------------------------------------------
   Tokens.

   The stage colours are an ORDINAL ramp — one hue, stepping darker as a project
   advances Idea -> Prototype -> Beta -> Live — because the stages are ordered,
   not arbitrary categories. Retired is deliberately outside the ramp: it is an
   inactive state, not a further step, so it takes neutral grey and recedes.

   Both ramps are validated against their own surface (monotone lightness,
   >=0.06 lightness gaps, single hue, end step clears the surface). Colour never
   carries a stage on its own — every swatch sits beside its written label.
