/* ---------- the level-up: a firmware update (levelup-view.mjs, levelup-ui.mjs) ----------
   A compact flash screen under the top bar (docked over the prompt on a phone; app.js sets --lu-top and --lu-bottom
   from the top bar's and the prompt's boxes). It only comes up while no fight is up (levelup-ui.mjs), so it never sits
   over the fight board. An amber kicker strip, the level in a dot font (teal: yours) beside the flash's progress line,
   then [ OK ] per unlock once the flash is done. Each row takes no room until it lands, so the panel grows a row at a
   time and never shows an empty block. Amber for what you get, teal only for your level, violet for a daemon slot.
   Continue (Enter), Esc or × close it. Motion off or reduced motion: everything is there at once. */
