   No .wrap ancestor here on purpose (the section is already edge-to-edge) —
   padding on the strip itself gives a plain, uniform gutter instead of
   trying to match .wrap's own inset with a computed margin.
   justify-content: safe center is the fix for "stuck to the left": a flex
   row defaults to flex-start, so on any viewport wide enough that all 7
   images fit without needing to scroll, they bunched up on the left with
   empty space on the right instead of sitting centered. `safe center`
   centers the row when it fits, and only falls back to start-alignment
   once content actually overflows and needs the scrollbar — never clips
   the first item off-screen the way a plain `center` would. */
