/* ── Device: a laptop whose lid opens as you scroll ────────────────────────
   Drawn, not photographed, and unbranded — flat planes on the hairline scale,
   no gradients, no shadow. The lid is a real 3D rotation about a hinge at its
   bottom edge, so the screen foreshortens as it swings up the way a lid
   actually does. `--open` is 0 (shut) to 1 (upright), driven by scroll. */

   A laptop drawn in CSS, no branding anywhere on it. The old version was two
   grey rectangles and read as a diagram; this one has the proportions of the
   real thing — thin uniform bezel, notch, tapered base with the lip cut out of
   the front edge — because the section's whole argument is "here is what your
   desk actually looks like".

   Depth is gradients only. No box-shadow anywhere: the design system forbids
   them, and aluminium reads as aluminium from a light gradient across it.

   Two scroll-driven variables:
     --open  0 → 1   the lid lifts
     --wake  0 → 1   the lock screen lifts away, revealing the desktop
   The wallpaper sits under both and never restarts, which is the feature.
