/*
 * The app's loading screen. Shown by index.html before any JS runs (on a
 * visit or refresh) and by AppLoader (src/components/shared/app-loader.tsx)
 * while a route's code downloads. Plain CSS on purpose: it has to render
 * before the app's own stylesheet exists, so it carries its own tokens.
 *
 * One of nine pictures plays while the status line cycles, each a thing
 * a shop counts, keeps or does. index.html picks one at random for a visit
 * (data-boot-scene on <html>) and BootScene
 * (src/components/shared/boot-scene.tsx) carries it on:
 *   abacus   beads slide across one after another and click into place,
 *            then go home in the opposite order
 *   files    three folder tabs rise one after another, like files being
 *            flipped through
 *   receipt  a till feeds out a slip, line by line, then it's torn off
 *   crates   three crates land on a shelf and are carried off
 *   scale    a pair of scales rocks, its pans staying level
 * and, for what the app has learnt since (Israel, 10 October 2026):
 *   rider      a delivery bike with a parcel on its rack, wheels turning
 *   swap       a phone and a boxed one trade places, and trade back
 *   checklist  a clipboard's three boxes are ticked off in turn
 *   scan       a scanner's line runs down a barcode label and back
 * Nothing shows for the first 400ms, so a fast load never flashes it;
 * after 8s a note offers a reload.
 *
 * Brand colours (web/docs/design/DESIGN_SYSTEM.md 6): mint, gamboge and
 * blue things with ink on paper, a dotted track, no shadow. The colours
 * stay in dark mode; what is drawn in ink turns pale, where ink would
 * vanish.
 *
 * .tabs-boot--inline is the same loader inside the page, under the top
 * bar (components/shared/business-opening.tsx).
