/* =====================================================================
   Mobile Horizontal Scroll — Card Sections

   Pattern: negative margins break the grid OUT of .container's 20px
   padding so the track spans the full viewport width (0 → 100vw).
   padding-left restores the visual indent for the first card.
   padding-bottom must cover both the entry-animation translateY(32px)
   offset AND card shadow bleed, so overflow-y:auto (coerced by
   overflow-x:auto) does not clip cards during the transition.
   Card widths in vw units are viewport-relative, not container-relative.
