/* --- 10f  Obstacle → response --- */
/* --- 10f  Obstacles ------------------------------------------------------
   Full-bleed tool-rack photography under a heavy Oil scrim, with the copy in
   raised cards. Worst case (a pure-white pixel behind the scrim) still
   composites to about rgb(34,26,28) inside a card, so body text holds ~17:1
   and the yellow quote ~10:1. The photo can be swapped without re-checking.

   The photo is held at viewport height and made sticky rather than stretched
   over the whole section. Stretched, its box was the section's height — 3019px
   at a 320px viewport, because six cards stack — so object-fit:cover upscaled
   a landscape frame 7x and showed 7% of its width: a blurred vertical sliver.
   At viewport height the box is always roughly viewport-shaped, which is close
   to the photograph's own proportion, and a 3:4 crop is art-directed in below
   760px so phones get a composition rather than a slice.

   NOTE: do not add overflow:hidden to .obstacles-section or .obstacles__media.
