/* ---- Outline-only letterforms (STUDIO & .FOUNDATION, the 3 discipline

   -webkit-text-stroke on transparent-fill text was rendering stray
   fragments inside the letterforms on some devices — a real rendering
   bug in that specific CSS property, confirmed still present after
   removing text-transform and lowering the weight (neither is the
   actual cause). A text-shadow-ring fake stroke was tried next but
   text-shadow paints a solid dilated silhouette, not a hollow outline,
   so it just filled the letters solid instead.
   This uses real vector stroking instead: the visible text stays a
   normal (invisible, color:transparent) inline-block for accessibility
   and layout sizing exactly as before, and an absolutely-positioned SVG
   <text> — a completely different, correctly-hollow rendering path —
   draws the actual outline on top, sized to match its wrapper exactly
   (no manual width/viewBox math, no separate responsive scaling to keep
   in sync with the rest of the heading/list). */

     not the stroking method. This is the one remaining variable fully
