/**
 * demo_loading.css — full-screen progress overlay shown while a demo provisions.
 *
 * Markup: templates/components/demo_loading_overlay.html
 * Behaviour: static/js/controllers/demo_loading_controller.js
 *
 * Design tokens (--orange, --sandstone, --black) are defined in
 * chippie-marketing.css :root; this file loads alongside it in the
 * public_base.html head, with literal fallbacks for safety.
 *
 * The fill is driven by width transitions (not a fixed keyframe) so completion is
 * a real signal: .is-active eases the bar toward 90% while the POST is in flight,
 * then .is-complete carries it the rest of the way to 100% before the controller
 * navigates. Transitions compose, so the snap-to-100% starts from wherever the bar
 * currently sits — no reset-to-zero jump. Removing the classes (bfcache restore via
 * the back button) returns the bar to zero for the next run.
