/* ==========================================================================================
   preload.css — 首页的「资源预下载」浮标与面板 (public/js/preload/panel.js).

   Sizes are px, not the game's rem scale: 1rem is 100 design px at 1920×1080 but never drops below
   40px (theme.css), so a .24rem panel on a phone in landscape would come out ~10px tall. This is a
   utility overlay — it has to stay readable at any viewport, not scale with the battlefield.

   z-index 190/195: above the game's screens (max 200 is the modal layer, which should still win).
   Colours fall back to the literals so the panel survives a page that never loaded theme.css.
