   The highlight (.sz-seg-thumb) sits ABOVE the items and moves with transforms only, so the browser's compositor
   runs the slide even while the page is busy (e.g. the landing page booting):
   - the light pill is three 38px rounded pieces (.sz-seg-p) at the pill's left edge, centre and right edge;
     their union is the pill at any width from 38 to 81px, and each piece only ever translates;
   - .sz-seg-win is a pill-sized window (translate + scaleX) holding a dark copy of every label and a black
     logo (.sz-seg-ink), counter-transformed so the copy never moves. So each label is dark exactly where the
     highlight covers it and normal (grey / orange) elsewhere, at every frame of the slide.
   site-src/nav.js animates the same transforms (Web Animations API) between these resting states. */
