/* loading-states.css — #A5 honest streaming load detail.
 *
 * The garage-door overlay already shows a real % (GLTFLoader byte progress).
 * This adds an honest ETA + a car-silhouette skeleton, revealed ONLY while a
 * load is actively "streaming" — i.e. it has outlasted ~400ms or runs on a
 * remote host (set as `.is-streaming` by setViewerLoading() in app.js). On a
 * fast localhost load the class never lands, so the door stays clean and these
 * never flash (PLAY §1: under ~300ms, show nothing).
 *
 * Kept in its own file so it commits cleanly — css/viewer.css carries
 * unrelated other-session WIP.
