/* SPRINT_LOG 651 R4 - THE GAME'S OWN LOADING SCREEN FROM THE PAGE'S FIRST PAINT. The picture is the
   shell's boot cover drawn by the game (web/loading.png, probes/pkg651/R4/capture_boot.gd): the
   1152 x 648 design canvas at 4x. `object-fit: contain` scales it as the game's canvas_items stretch
   with `expand` does - min(w / 1152, h / 648), centred - and the page's background is the game's.
   The bar's fill is drawn over the picture's bar; the overlay stays until the game says its own
   cover is on screen (fcBootHandoff), so no other picture is ever shown. No Godot splash, logo or
   progress bar. */

   browser that cannot compile the programs in the background still links them one at a time, 2-3 s a frame). Until 707
   they sat with "Preparing the street" in the menu's lower right corner (#666 R2.2's #fc-prep); the menu's indicator is
   the game's own now. The cover's column is centred on the canvas, which is the 1152 x 648 design scaled by
