   aCXend — Case Studies (page-scoped)
   Loaded ONLY on case-studies.html and sample-case.html, after effects.css.
   Adds NEW classes only (.case-grid, .case-card, .section--textured, …).
   Nothing here overrides an existing selector — it reuses the shared design
   tokens (color, radius, shadow, motion) so the cards feel native to the site.
