   The four line-work patterns. Hairlines stay 0.75 to 0.9px at any size
   (vector-effect inside the SVG), so elegance comes from placement and
   opacity, never from weight. Each layer fades in when its section arrives
   and drifts slower than the page (data-p) so the type reads as printed
   over the drawing rather than glued to it. */
