/* ==========================================================================
   CHALKLINE — Interior design & renovation, Tai Seng

   One aesthetic: plan in hand. Ink linework on skim-coat white for
   structure, photographs for proof, and one blue — the blue a chalk line
   leaves on the screed — for anything new. Every colour pair below was
   measured (ratios in the comments); the muted tone is the one that fails
   in practice, so it never sits on the screed grey.

   Radii are zero except on pill buttons. There is no decorative grid.
   The only rules on the page are the ones that separate a line item
   from its total.
