/* CIBG Huisstijl (a customized Bootstrap 5.2 build) is loaded as a plain <link> in
   index.html (public/cibg-huisstijl/css/huisstijl.min.css) so its relative url(../fonts|
   icons|images) references resolve at runtime.

   Token bridge: the app's components reference a semantic `--rhc-*` token vocabulary
   (316 refs, 54 tokens). Rather than rewrite every reference, we redefine those tokens
   HERE onto CIBG/Bootstrap values (--bs-* where one exists, CIBG palette hex otherwise).
   The names are now an internal alias set; the VALUES are CIBG. (styles.scss is exempt
   from check:tokens, so palette hex is allowed in this one file.) */
