/* =========================================================
   SmileAge — Login page styles
   -----------------------------------------------------------
   Every selector is namespaced "sa-login-" so nothing collides
   with style.css (untouched) or any other page's CSS file.
   This is the one page on the site with no shared header/
   footer — it's a standalone destination, not part of the
   marketing-site navigation shell, so it gets its own fully
   self-contained visual treatment: an animated gradient-mesh
   backdrop behind a frosted glass card.
