/* ====================================================================
   Jumpingjump — Spinner
   --------------------------------------------------------------------
   Self-contained loading indicator. The dot hops on top of a rotated
   foam-block — same brand mark as the logo wordmark, isolated.

     <span class="jj-spinner jj-spinner--xl"></span>
     <!-- color override (any CSS color or var) -->
     <span class="jj-spinner" style="--jj-spinner-color: #FF5B22"></span>
     <!-- speed override -->
     <span class="jj-spinner" style="--jj-spinner-speed: 1.6s"></span>
