/*
  TapDeck — w4 visual world
  THESIS: a payments site shaped like the POS terminal's own control panel;
          refuses the light SaaS brochure and its three feature cards.
  OWN-WORLD: near-black charcoal field throughout (#0d1014) — POS lives in dim
             bars and kitchens — with signal lime (#c6f24e) and cyan (#3ad6c6),
             a keypad grid motif and mono numerics for every amount.
  MOTION: one authored moment — the keypad keys light in sequence, then a charge
          pulse crosses the terminal.
