+- Add matching T5/T6 round-start reminders using the latest usable cached map
+  record. Show at gaps of 20, 15, 10, 8 and 6 rounds, then every round for the
+  final five. Show matching/overtake milestones, then stop reminders after the
+  first overtake for the rest of the match. Milestones distinguish reaching a round
+  from saving the result after match completion; `.leaders` remains available.
+  Listen to the stock `start_of_round` event so reminders follow the actual
+  start, including on T6 where the counter advances during the round break.
+  Ignore duplicate starts and counter rewinds within the match.
+- Common renders a compact record header and one proximity/milestone line for
+  six seconds, using two nonarchived elements in the existing service area.
+  Keep full join/`.leaders` announcements, all tied holders and 12-second pages.
+  Skip pending or active help/records, unready players and recent welcome/manual
+  record requests; opening help discards a reminder. Release elements on idle,
+  interruption, disconnect and game end. Both games work without optional HUD.
+- Reuse the cache without round-triggered HTTP requests. Empty, unavailable or
+  expired records suppress reminders; skipped reminders are not queued.
+- Compatibility: leaderboard `1.2.0` requires matching common `1.5.0+`.
+  There is no new native-plugin, backend or upstream dependency requirement.
+  Unchanged HUD, AFK and other scripts retain their individual versions.
+- Validation: 169 leaderboard, 14 core HUD, 72 service HUD, 42 bank, 17 join,
+  23 telemetry and 39 AFK portable checks passed, as did both moderation
+  script checks. All nine T6 scripts compiled/assembled with upstream gsc-tool
+  `8f1d6bd` libraries; the final changed common/leaderboard sources were rechecked
+  after the event-timing fix. JSON uniqueness, all 18 script manifest entries,
+  version/changelog consistency, local documentation links and `git diff --check`
+  passed. Portable checks use engine shims; no live Plutonium validation or
+  backend integration was performed. T5 has no gsc-tool compiler backend.
+- Deployment: copy the updated leaderboard and common scripts together for
+  each installed game, then restart the map. No full server-process restart is
+  required for this script-only update. No deployment performed. Live T5/T6
+  rendering, readiness and round-transition validation remain required; see
+  [record validation](README.md#map-record-announcements).
