//! Apex fresh-visitor landing — the product front door at
//! `localharness.xyz` for a visitor with NO identity.
//!
//! Hoisted out of the wasm-gated `app/` tree (same pattern as `raster.rs`
//! / `compose.rs`) so the exact shipping markup renders NATIVELY: the
//! `landing_preview` test below writes `target/landing-preview.html`
//! (stylesheet linked relatively into `web/`) so the page can be
//! screenshot-reviewed without an identity-free browser profile.
//! Regenerate with:
//!
//! ```sh
//! cargo test --features browser-app landing_preview
//! # then open target/landing-preview.html
//! ```
//!
//! Funnel: ONE decision — create a wallet. The fresh-visitor front door is a
//! single `create wallet` CTA (the paid entry: it creates AND funds the
//! wallet, so there's no unfunded-wallet path and no 0-$LH name-squatting).
//! Invited users skip this entirely — an `?invite=CODE` link/QR auto-redeems
//! on mount (`app/mod.rs` → `try_redeem_pending_invite`). Redeeming a code and
//! importing a seed are recovery/edge paths and live in the admin panel, NOT
//! here. Explore is post-auth only (no account yet → nothing to browse).
