//! `vL()` — secret-feed builder. JS reference:
//!
//! ```text
//! function vL() { return jw(hP(pf() || gC(365)), vJ); }   // vJ = 10
//! ```
//!
//! In JS, `pf()` returns the page fingerprint; here the caller passes
//! whatever bytes the runtime would have collected. The fallback
//! string is tenant-specific (decoded as `gC(365)` in the captured
//! init.js) — clients select the right fallback via the tenant
//! profile (ADR-0024 N5).
