   viz.css  —  reusable infographics + progressive disclosure
   --------------------------------------------------------------------------
   Self-contained under .tb-viz / details.tb-more. Loaded only on pages that
   opt in. Reuses the site's --serif; declares its own colour tokens so it is
   safe anywhere. Pure CSS (no JS): pipelines animate on load, outcome bars
   fill on load, and the "Read the detail" blocks use native <details>.
