Event verification
Use the in-game event panel or official store listing as the primary source. Social posts and videos can supplement details but should not override the dates shown in the game.
Progress requirements
Explain exactly which levels or matches count. If progress is inconsistent, note the observed conditions instead of presenting a guess as a rule.
Limited rewards
Separate guaranteed milestone rewards from random drops and paid offers. Players should know what can be earned without a purchase.
Archive value
Expired event pages remain useful when they document mechanics that return. Add an ended label and link to the current event hub.
