 *   PATCH /engagement/streaks/override          — override a single streak
 *   PATCH /engagement/leaderboards/override     — override a single leaderboard
 *   PATCH /engagement/achievements/override     — override a single achievement
 *   POST  /engagement/overrides/clear           — clear all / by type / by entity
 *   GET   /engagement/stats                     — counts + active users
 *
 * Entity definitions live in application code and are synced to the
 * platform on SDK init (`lastSyncedAt`); Console overrides let operators
 * tune an entity without redeploying. Clearing an override restores the
 * code-defined default.
