/* References index and portfolio pages (uploaded by tools/import_references.py).
   Colours come ONLY from the site.css :root tokens (--vual-*), which every
   frontend page loads: no teal, forest, sage or cream literals (VUX-04).
   tools/test_qweb_lint.py fails the build on a hex colour in this file.
   Logo marks are shown at their natural size at most, never upscaled (VUX-10).
   Motion (DESIGN.md "Hareket (motion) sistemi"): F1 hover only, through the
   --vual-* tokens; hover movement in (hover: hover) and (pointer: fine) and
   (prefers-reduced-motion: no-preference). This file goes live through the
   data step tools/import_references.py --apply, after the module upgrade that
   defines the tokens; without them a transition or zoom simply does not run,
   and the mark-card ring falls back to the old 1px rule. */
