/* AILA configurator, round 10. Colours, fonts and motion come from ../brand/brand.css (generated from the
   brand folder). Two lights, one object: Paper (day) and Night.
   The model of the owner's company is the hero of every step; the guide beside it (beneath it on a phone)
   asks one question at a time, value first, with the price in one quiet line beside the one button.
   Type: one display, one heading, one body and one label size per screen class:
     laptop 52 / 30 / 18 / 13 · phone 32 / 22 / 16 / 12 · meeting room (Present) 64 / 36 / 22 / 15.
   Spacing comes from one scale: 4 8 12 16 24 32 48. */
