/* ------------------------------------------------------------
   SIGNATURE TECHNIQUE: cross-document View Transitions (MPA).
   The single rule below opts every same-origin navigation into
   the View Transitions API. The header wordmark carries a named
   transition (view-transition-name: studio-logo) so it morphs
   smoothly from its position on one page to its position on
   the next, while the rest of the page cross-fades.

   FALLBACK NOTE: there is no @supports test for at-rules, and
   @view-transition is itself the opt-in — browsers that do not
   implement cross-document view transitions (or MPA navigation
   capture) simply ignore this block and perform an ordinary
   instant navigation. Nothing breaks, nothing is hidden behind
   the feature; the site is fully usable without it. Where we DO
   feature-test (the ::view-transition pseudo tree styling), we
   guard with @supports (view-transition-name: none) so
   non-supporting parsers skip the whole block cleanly.
