/* ── project gallery ────────────────────────────────────────
   A scroll-snap strip: the browser handles the swipe natively,
   so it keeps its momentum and feels right under a finger.

   The strip takes every pixel the page has left over rather than a
   fixed height, so the work is shown as large as the screen allows.
   The image is positioned rather than sized in percentages: a
   percentage height here resolves to `auto`, because the slide's own
   height comes from being stretched inside the flex strip and
   browsers treat that as indefinite — which silently clipped the
   middle out of every render. Absolute insets have no such problem.
   Images are letterboxed, never cropped: the whole render is
   always visible. */
