   Breakout approach: the grid lives inside .container (max 1100px, centered).
   Instead of transform (would stack with nothing here, but margins are the
   more predictable option — no new stacking context, no interplay with
   .fade-in transforms), we widen the grid to min(1280px, 100vw - 3rem) and
   center it on the container's centre with a negative-capable margin-left:
     margin-left = 50% of container − half of grid width
   Because .container itself is centered in the viewport, the grid ends up
   centered on the viewport too. The 3rem subtraction keeps a 1.5rem gutter
   on each side (> any scrollbar width), so no horizontal page scroll.

/* ==========================================================================
   MOBILE OVERFLOW FIX
   Append-only block — nothing above is rewritten or removed; relies on the
   cascade (these rules come last and override earlier ones).
   Purpose: kill horizontal page scroll on mobile (tested at 375px, rules
   apply at <= 768px). !important is used ONLY in the breakout-cancel block
   so the calc()-based breakouts (.screenshots-grid / checklist :has()) are
   guaranteed to be overridden regardless of selector specificity.
