/* ---- sheave (Sheave — Bearings, belts & drives 176) ------------------------
   THE STRUCTURAL MOVE: the page is a light–dark ladder. Every contained column
   stands on zinc white, and exactly twice it breaks its container and drops to
   full-bleed oiled-steel charcoal — the six-up capability strip and the four-up
   strip near the foot — with the contact band closing on that same ground.
   There is no photograph in the library for a strip tile and none is invented:
   the empty media box is redrawn as a small orange bearing ring above a centred
   label, and the lower band strips the ring out entirely so it reads as four
   text blocks on flat steel. That band is matched by CHILD COUNT, never by
   element position, because both strips are <section> and the hero is first.
   Product tiles are the only pure white here, separated by 1px zinc gaps rather
   than card borders, so the shop floor is the brightest thing on the page. One
   machine orange — buttons, ring, rand figures. Headings stay graphite. */
