/* ============================================================
   OpenBooth — Theme "halftone" (Swiss silver poster)
   Silver metallic paper + all-over halftone dot texture, very
   large light-weight grey display type, cobalt blue RESERVED for
   key data (money / dates / CTA). Rounded speech-bubble pills hold
   the numerals; hairline rules; three tiny nav-dots. Institutional-
   futurist, cool, precise, quiet.
   All selectors scoped to [data-theme="halftone"].
