   app.css — emulator shell chrome only.

   No card styling lives here — every card's CSS installs itself via
   PK.register when its render.js loads (shared/preview-kit.js). This file is
   the meta chrome around that: the household picker, the top bar, the
   app-shell frame (header pinned / body scrolling / nav fixed), and — since
   Phase 2 — the flow shell's own bar plus the provisional-step form/summary
   chrome, ported from workflows/anti-parasite-flow/preview.html's own
   <style> block (same classes, same purpose: harness, not product UI).
   --------------------------------------------------------------------------- */

     since that only kicks in once its parent box stops growing to fit it.
