   Ductus breaks from every prior skeleton in this project: the
   hero is not a passive canvas to scroll past — it is a working
   tool (a live variable-font specimen tester with real sliders).
   Palette is stark print-specimen: true white, true black, one
   saturated indigo accent — no dark background, no warm paper.
