  /* ---------- Figures: pan, don't shrink ----------

     The figures are hand-tuned drawings on a 620- or 660-unit viewBox. Letting
     them fit the phone width scaled them to 0.49x and dragged the type down with
     them: 12-unit labels landed at 5.8px, i.e. unreadable. Scaling the type back
     up in CSS was measured and rejected — these drawings have under 25% of
     horizontal slack before labels collide with each other or run out of the
     viewBox (the 660x200 query figure breaks first, at ~1.3x), and closing a
     2x deficit needs ~1.9x.

     So: hold every figure at its natural 1:1 size and let the card pan. A
     uniform scale preserves the drawing exactly — nothing is re-laid-out, only
     the window onto it is smaller than the whole.

     Why an explicit min-width and not an intrinsic keyword: an <svg> carrying
     only a viewBox has no CSS intrinsic width. width:auto, width:max-content,
     width:fit-content and min-width:max-content were all tried here and all
     resolve to the container width — they parse, compute, and do nothing. The
     px value is the viewBox width, so it must be kept in step with it. */

   600px, not the 720px above, is where this turns on: the rule needs to promise
   something true, and at 620px of drawing against (100vw - 76.8px) of card the
   620-unit figures only start panning below ~697px. At 600px there is ~100px to
