/* ---- students collage — full-bleed, scroll-driven proof moment ----
   A dark island inside the light .proof section — matching the dark/light
   rhythm the rest of the site uses (hero/macro/method are all dark), so this
   doesn't read as a break in the pattern. As it scrolls into view the image
   band wipes in from right to left (JS scrubs its clip-path), revealing the
   collage — following the same scroll logic as the rest of the site.
   It's a direct sibling of .container (see index.html), so it spans the
   section's full width natively — no 100vw/50vw math, which is fragile
   whenever a scrollbar makes vw and % disagree.
   The band is locked to the image's REAL aspect ratio so the photo is never
   cropped: on desktop it's a wide cinematic strip with the caption over its
   darkened base; on mobile it becomes a shorter ribbon with the caption
   stacked cleanly above it (a headline would never fit legibly on top of a
   short, wide image). */
