/* Sharetru · Exploded view with parts list (2026)
   The module's own styles. Section, head, question card and buttons use Shared styles (st26); colours are the
   ST26 tokens, so light and dark both work. The drawing is HTML, not SVG: each layer is a square turned into an
   isometric plate (rotateZ(-45deg) then rotateX(60deg), no perspective), with its thickness drawn as a box-shadow
   offset in the plate's own coordinates so it lands straight down on screen. One registered custom property,
   --xv-s (0 = stacked, 1 = exploded), spaces the plates; it animates on a view timeline bound to the figure (no
   scroll-jacking), plays once where view timelines are unsupported (module.js adds .js-once / .in), and stays at 1
   under reduced motion, with the theme's "Allow motion" off (html[data-motion="off"]) and in print. Pointing at a
   row lifts its plate and pointing at a plate marks its row, with :has() alone. Built for the Aerospace and defense
   page, 19 Oct 2026; no other page carries it. */
