   Layout: Carousel
   -----------------------------------------------------------
   Containment strategy:
   The carousel sits inside a chain of flex containers (Oxygen's
   .ct-div-block is display:flex). Flex children have min-width:auto
   by default, which lets them grow to fit their intrinsic content
   — for us that's 12 thumbnails at ~1280px each, ~15000px total.
   To stop that growth from breaking the surrounding layout we:
     1. Cap our outer wrapper at 100% of its parent
     2. Set min-width:0 along the chain so flex shrinking can occur
     3. Use `contain: inline-size` so layout effects don't escape
     4. Use overflow:hidden as a final guard
