/* =========================================================================
   Chalkline Climbing + Fitness — demo gym site.

   Concrete grey walls, chalk white copy, and headings set in the colours of
   the holds. Colour is the whole identity here, so it has a job: every hue
   below belongs to a class, and the same class is the same colour on the
   schedule, in the class list and in a member's booking history.

   Deliberately nothing like carterlong.net (deep petrol, blue and green),
   Northline (pale ice and navy) or Emberline (warm bone and charcoal). Three
   demos that share a look are one demo shown three times.

   Contrast was measured, not eyeballed. Every hold colour below clears 4.5:1
   as text on all four concrete surfaces, and every control border clears 3:1.
   That is why the greys are dark: bright saturated colour on mid grey fails,
   and the fix is always the background, never the colour.
