/* ==========================================================================
   SPINESTECH — Case Studies Archive — "THE FILE" redesign
   Scoped under .page-case-studies. No Tailwind, no framework.

   CONCEPT
   This page shows delivered platforms — real case files. The whole
   redesign leans into that literally: foil-stamped dossier numerals,
   parchment case-file cards on a near-black ink background, monospace
   reference codes, and viewfinder corner-brackets on every framed image
   (like an inspector clipping evidence photos to a folder). Motion is
   one deliberate cinematic gesture (a scan-line pass on the hero) plus
   quiet hover physics — nothing scattered.
   ========================================================================== */
