+/**
+ * pgamdirect Analytics Adapter.
+ *
+ * Publishers include this module alongside `pgamdirectBidAdapter` to
+ * forward Prebid auction telemetry to the PGAM Direct SSP backend.
+ * Companion to the server-side bid-outcomes ledger we maintain from
+ * the bidder — this module gives us CLIENT-confirmed signals that
+ * the RTB path can't see:
+ *
+ *   AUCTION_END   — final state of every auction (who we competed
+ *                    against, at what prices). Lets us see
+ *                    competitor CPMs without needing their
+ *                    reports.
+ *   BID_WON       — which bidder won in the Prebid layer and what
+ *                    they paid. Critical for our reconciliation
+ *                    because a server-side win notice doesn't tell
+ *                    us if the publisher actually rendered the ad.
+ *   AD_RENDER_SUCCEEDED / AD_RENDER_FAILED — client-confirmed
+ *                    impression. Feeds the discrepancy reconciler
+ *                    so we can distinguish "bidder said we won" from
+ *                    "user actually saw the ad."
+ *
+ * Configuration (publisher-side):
+ *
+ *   pbjs.enableAnalytics({
+ *     provider: 'pgamdirect',
+ *     options: {
+ *       orgId: '<your pgam org id>'          // REQUIRED
+ *       // endpoint: 'https://...custom...'   // optional override
+ *     }
+ *   });
+ *
+ * GVL ID: 1353 (same as the bid adapter, PGAM Media LLC).
