/* ═══════════════════════════════════════════════════════════════════════════
   Studio hero art: a miniature of the designer, in the .part window of
   /product-art.css (frame, title bar, tokens). Loaded on /studio/ only.

   The scene is one ~10 s loop, ease-in-out, and runs ONLY under .is-playing
   (main.js toggles it while the art is on screen):
     0.8-2 s   a tank glides from the palette onto the canvas and settles
     2.5 s     it is selected (soft accent outline), the inspector fills in
     3.2-3.7 s the binding chip "EQTank/Level" appears
     3.8-5.2 s the level fills 0 -> 62 %, then "Live from Nexus" shows
     5.5-6.5 s the cursor goes to Publish and clicks
     6.7-8 s   the beam runs under the toolbar (the one beam use: Raylux is
               working), then a "Published" toast
     9.5 s on  it fades and resets
   Without JS or under reduced motion the base styles below are the finished
   still frame: tank placed, selected and bound, no beam, no toast.

   Shared primitives defined here (part-studio- prefix): seg, pill, tree,
   inspector row, cursor. The operator screen keeps the fixed HP grays and
   steel blue (Raylux HMI Color Standard): they are the same in both themes.
