/* ── Shared carousel base ─────────────────────────────────
   Common styling for any kokoto carousel (image or features).
   Variant files (carousel.css, features-carousel.css) layer on
   element-specific rules (img sizing, text slide layout, …).

   Scoped to .carousel so it only touches Bootstrap carousels.
   Variant rules use their own modifier class (.c-img, .c-text)
   so two carousels can live on one page.
