   Opening splash — a faithful port of the AIBuild app splash:
   squircle brand mark springs in, rainbow ring draws around it,
   sheen sweeps the tile, the AIBuild letters BUILD UP one by one
   (rainbow band + window-grid texture, revealed from the ground
   up) above a growing rainbow foundation; tagline fades up.
   Shown once per browser session on the home page. It then waits:
   the hint asks the visitor to move the logo's arrow up (drag,
   swipe, wheel or key; main.js sets --lift / --p while it moves),
   and the splash lifts away like a curtain. Click still skips.
