   HiVi Labs — Calculator data-visualisation primitives
   Shared, lightweight SVG viz used by every calculator readout
   (home Velocity + Agent ROI, and the /calculators page's
   Tech-Debt + Automation). Driven by static/js/calculators.js.

   CONTRACT (so markup + JS stay in lockstep):
   - A viz element carries  data-viz="<key>"  matching a key returned
     by that calculator's CALCS[type].viz() in calculators.js.
   - The JS sets the custom property  --pct  (0..1) on that element.
     CSS animates the bar/ring from --pct via transition (no JS rAF
     for the shape — only for the count-up numbers).
   - An optional descendant  [data-viz-num]  is count-up animated by
     the JS to the metric's value (format chosen by the JS viz map).
   - Colour is themed by a modifier class (--warn / --teal / --accent);
     default is neutral. Modifiers set --cviz-color / --cviz-track.

   Everything degrades gracefully: missing key -> stays at 0; no JS ->
   bars/rings sit at their --pct default (0) and the numeric result
   cards still show the real figures.
