/* ==========================================================================
   Singapore TOTO — Data-Driven Number Generator
   Design goal: clean / modern / trustworthy / data-oriented — NOT a casino
   look (no neon, no gold, no slot-machine motifs). Mobile-first, then
   progressively enhanced for tablet/desktop (see breakpoints at the bottom
   of each section below: 640 / 768 / 1024px).

   IMPORTANT (see project history): a previous project (01-korea-lotto) had a
   production bug where `overflow: hidden` on a flex-height container blocked
   vertical scrolling on real iPhones. This file deliberately avoids:
     - overflow: hidden on html/body or any full-height layout container
     - height: 100vh / 100dvh locks on scrollable containers
     - position: fixed wrappers around scrollable content
