   tools-chart.css — SHARED chart primitives for every design variant.
   Loaded on every casino-tools-N page AFTER the theme stylesheet. Each theme
   defines the --k* custom properties; the same tokens are read by tools-core.js
   for the inline SVG fills, so charts always match the active design.
   Theme contract (define these on .lab):
     --k1 primary/positive   --k2 reference   --k3 neutral   --kr risk
     --kgrid grid+axis line   --klabel tick/label text   --kvalue value text
     --kband band fill        --kband2 lighter band fill  --kmono chart font
