/* ===========================================================================
   The chart layer.

   Palette derived from Torqfolio's own tokens and validated, not eyeballed --
   scripts/validate_palette.js from the dataviz method, run against #ffffff,
   the color these cards actually render on:

     categorical (adjacent pairs: bars, stacks, lines)  ALL CHECKS PASS
       worst adjacent CVD  green<->blue  dE 15.8 (deutan)
       worst adjacent normal-vision      dE 17.7
       all four clear 3:1 on white
     ordinal ramp, brand hue (the listing pipeline)     ALL CHECKS PASS
     status vs white   good 4.47:1  warning 3.14:1  critical 4.43:1

   The all-pairs pairlist caps at TWO slots, so nothing here is a scatter,
   bubble or map. Only adjacent forms are built, which is what that pairlist
   covers.

   Single theme on purpose. #mechanicApp hard-sets a light background, so a
   chart in here can never land on a dark surface; a speculative dark palette
   would be tokens that are never exercised and never validated. If the
   workspace ever gains a real dark mode, re-step these against that surface
   and run the validator again -- do not flip them.
