// Home route = Hem (concept scene 14): greeting + Att göra + Fortsätt.
// The KPI/revenue/deadline widgets left the page (founder direction,
// dev_docs/last_session_resume.md §8), which also pruned their fetches:
// the journal-line YTD aggregation, unpaid-invoice totals and deadline
// queries are gone and the page got faster.
//
// Streaming: the page itself awaits only what the greeting shell and the
// redirects need (settings, profile, agent profile, the Skatteverket flag).
// The notice line, the setup checklist and the Att göra + Fortsätt panes are
// async server components behind their own <Suspense> (hem-sections.tsx),
// so ~30 queries fill three blocks in as they land instead of holding the
// whole page behind the slowest one. RSC streaming applies to client
// navigations too, not only hard loads.

  // and open the cockpit from the nav when they want it; the middleware's

  // has nowhere else to land. companyId above can be the middleware's
  // fallback (which it also writes back to user_preferences, so the DB can't
  // tell picked from auto-picked); the session cookie stamped by
