/* ============================================================================
   GSS Interactions — site-wide SOURCE OF TRUTH for hover/focus motion + colour.
   Enqueued on every front-end page (mu-plugin gss-interactions.php), early, so
   every other surface sheet (gss-codex / gss-services / gss-listings /
   gss-nav-mega / gss-guide), the baked footer, and the discovery-form inline
   CSS can ALIAS to these tokens instead of each re-declaring its own. One
   duration, one easing, one CTA-hover green, one inversion palette, everywhere.

   PHASE 1 (this file, now): tokens only — purely additive, zero visual change.
   The variables sit inert until a surface sheet consumes them.
   PHASE 2 (later, staged to /review/): the shared interaction RECIPES
   (.gss-fx-invert / .gss-fx-raise contracts), the site-wide Ohio-balloon
   killswitch + link recipe, and the master reduced-motion block land here.

   Cache-busting: served under a version-STAMPED filename by the mu-plugin
   (this site strips ?ver and the CDN caches a year).
