/* Route Ledger V2 — motion & UX enhancement layer.
 * Loaded on top of styles.css; index.html stays untouched for comparison.
 * Concept: "the route draws as you climb" — content reveals like ledger
 * entries being pinned, and the process line draws with scroll.
 * All effects are gated behind .js-motion (added by js/v2.js) so the page
 * degrades to the static version without JavaScript. */
