   App Shell — shared dashboard chrome (Material Design 3)

   Reusable header / brand / button / title / snackbar primitives that give the
   ecosystem landing pages (mt, expense, present) the same identity as Slides.
   Lifted verbatim from slides/css/main.css so they are pixel-identical.

   MD3 tokens (--md-*) come from /css/shared.css and resolve in BOTH light and
   dark schemes. Classes are namespaced `shell-` to coexist with Tailwind.
