/* ============================================
   PAGE LOADER — branded boot screen
   Bounce adapted from Uiverse.io (mobinkakei), re-themed to the Enne
   palette: jade balls on the app background, logo mark above.

   Two modes, chosen by the inline controller in base.html:
   - cold landing: balls visible immediately, minimum ~0.9s display
   - .loader-quiet (internal nav): opaque background only — reads as a
     quick cross-fade; the bounce fades in only if the load is slow
