Epic 12: Prospect / landing

[Tar-ive]

Reshaped from docs/user-stories.md. Legend: ✅ Live · 🟡 Partial · ⚪ Planned.

Personas: Prospect

• 12.1 Understand the value fast ✅ — As a Prospect, I want the landing to show what Giftmaxxing does, so that I can decide to try it.
  • / hero, features, how-it-works, CTAs with real screenshots + branded social card.
• 12.2 Try it or join 🟡 — As a Prospect, I want a clear path into the app (or a waitlist), so that I can act immediately.
  • CTAs route into /feed; waitlist capture is client-side and not yet wired to a list.
