What this fixes

Three launch-readiness problems found in today's audit:

1. Landing page felt "cyberpunk", not posh (Bible issue #34)

The brand had already moved to the refined ivory "Email, considered." identity in app/layout.tsx (Italianno script wordmark, #f5f4ef ivory), but the landing page was still the old dark slate + neon blue/purple/cyan suite — and page.tsx overrode the layout with bg-slate-950.

All 12 landing components rewritten in the premium identity:

• Ivory + warm-ink palette, hairline borders, generous whitespace
• Playfair Display editorial serif for headlines (font-serif), Italianno script wordmark in nav/footer
• Racing-green #1f3d2e + brass #9a7b4f accents, no neon, no gradient blobs
• One dark "evening" band (#15281e) for the AI section and the closing CTA
• Copy aligned to "Email, considered." / "The inbox you'd sign your name to."
• Kept the zero-runtime CSS animation system (.enter-up / Reveal) — nothing added to the FCP path

2. First-run dead end after Google sign-in (Bible issue #33)

A fresh Google login landed on an empty /inbox with no path to the fully-built /onboarding wizard — this is why the dashboard looked "limited and bad."

• google/callback now checks /v1/connect/accounts and routes zero-account users to /onboarding (fail-open to /inbox on error)
• The inbox "all" empty state now shows "Connect your email to get started" with a button to the onboarding wizard (only when the user truly has no connected accounts)

3. No way to tell admin vs customer view

The sidebar footer now shows an owner/admin role badge next to the user's name (from /v1/auth/me). Note: the platform admin console is the separate apps/admin app destined for admin.alecrae.com — the mail app is always the customer view.
