   Layers, back to front: the midnight ground, the city (Scale: Dubai in points of light, WebGL, with Signal's
   shade over it), the stage (the blueprint grid, a canvas that shares the stage's camera, and the 3D world: one
   product and its campaign), the copy, and the proof row, where the tagline's three words double as the act
   indicator. Everything in the world is drawn in world units: 1 unit is 1 css px at --hx-2-k = 1, and 2.js scales
   the world to fit the room right of the copy. ?scale=field keeps the previous Scale (a field of screens). */
