   lucastang.dev — animated boot/desktop intro
   Monitor screen fractions (of assets/desk-photo.png, 1448x1086, re-measured
   via edge detection against the bezels) live in boot.js as SCREENS — the
   overlay divs are positioned in JS against the photo's actual object-fit:
   cover render rect, not fixed CSS %, so alignment holds at any viewport
   aspect ratio. See computeCoverRect()/updateMonitorPositions() in boot.js.
