/// <summary>
/// Phase 6 M2 — reputation screen (R key). Two columns:
///   1. **Factions:** strip of bars per known faction with NEMESIS..CHAMPION
///      colour banding + numeric standing.
///   2. **Recent contacts:** last N NPCs the player has personally
///      interacted with — name, role, current personal disposition,
///      trust ladder.
/// Plus a tail block showing the most recent ledger entries with their
/// reasons ("why does so-and-so hate me?" breadcrumbs).
///
/// Hidden factions (e.g. The Maw before Act I climax) are skipped from
/// the faction column; they still accumulate state internally.
///
/// In debug builds, F12 fires a synthetic "+5 Inheritor" event so we can
/// eyeball the cascade live without scripting a quest.
