/* ============================================================================
   FIVE MINUTE BUSINESS — Article visual components (.visual-*)
   Web redesign of the 9 schematic families. Light-paper, editorial, zero-JS.
   ----------------------------------------------------------------------------
   PORT TARGET: merge into public/assets/css/pages/article.css (replace the
   existing ".visual-* section"). Geometry decisions live here; the renderers in
   src/render/visual/<type>.ts emit the matching HTML class structure (see
   visual-render.js for the reference markup).
   Tokens consumed: --l-paper --l-bg --l-card --l-line --l-line-2 --l-text
   --l-muted --l-faint --azure --azure-700 --azure-soft --azure-line --steel
   --font --mono  (all already defined in brand-tokens.css / site.css).
