/**
 * PublicProfile (A1 Session 10) — the public ledger record for one handle.
 *
 * DATA SEMANTICS: every row here is a REAL settled ledger entry — outcome,
 * actual value, closing-line value. Nothing curated: publishing shows the
 * ENTIRE settled record, misses included. The header NEVER renders a
 * percentage under min_sample (20) settles — it shows RECORD BUILDING.
 *
 * Unknown and unpublished handles arrive as the same 404 — the page renders
 * one indistinguishable not-found state for both.
