/* Vibe Story: shared base. The looks live in css/theme-<look>.css, each scoped to html[data-style="<look>"]:
   paper  = cut paper, design concept A "Vystrihovačka" (default)
   blocks = the original toy-brick UI
   A new look = one more css/theme-<id>.css (+ its id in the <head> script of play.html and in js/ui/look.js).
   Markup is shared: .v-emoji = emoji pictures, .v-art = cut-paper drawings, .deco = paper-only ornaments;
   every theme decides which of them it shows. */
