/* ===========================================================
   sharenova.css — UI/UX upgraded baseline
   ===========================================================
   What changed vs. previous baseline:
   - Expanded design tokens (spacing scale, transitions, shadows,
     focus ring, surface variants) so JS pages stop sprinkling
     hex colors and one-off paddings inline.
   - True dark-mode-aware success/warning/error surfaces (no more
     #ecfdf5 / #fef9c3 hardcoded that go white-on-white in dark).
   - Skeleton system (.sn-skel*) with shimmer animation.
   - Spinner system (.sn-spinner) + button-loading state.
   - Toast system (.sn-toast-*) replaces alert() / confirm().
   - Modal system (.sn-modal-*) replaces native confirm().
   - Progress bar that's actually wired up (was defined but unused).
   - Sticky header gets backdrop-filter for the 2026 glass feel.
   - Responsive: explicit mobile breakpoints for product grid,
     buy sidebar, transfer mode-select, sales tables, admin queue.
   - Micro-interactions: hover lifts on cards/buttons, focus rings,
     fade-in for content reveals.
   - Mobile-first paddings: tighter on small screens, comfortable on desktop.
