/**
 * Deadly Threads — site-wide motion system (docs/motion-spec.md §M).
 *
 * Every effect is a reusable class, applied through Elementor → Advanced → CSS Classes or in theme
 * templates. Shared tokens only (style.css): --dt-dur-micro 160 · --dt-dur-ui 240 ·
 * --dt-dur-overlay 320 · --dt-dur-reveal 480; --dt-ease-entrance / --dt-ease-ui.
 *
 * Contract
 * - Animate transform / opacity / clip-path only (one documented exception: the Join the Yarn
 *   success tick stroke, M9).
 * - Pre-hide only under html.dt-motion (JS on, motion allowed, not the Elementor editor; 3s
 *   failsafe). Without JS, with reduced motion, or in the editor, everything is visible and static.
 * - Hover transforms only for (hover: hover) and (pointer: fine).
 * - Cart and checkout get nothing new.
