-- Module:AchievementSystem
-- Unified achievement module that combines data loading and achievement functionality.
-- This module: 1) Loads and caches achievement data from MediaWiki:AchievementData.json;
-- 2) Retrieves achievement information for users; 3) Renders achievement displays for
-- Person templates; 4) Tracks pages using achievements for cache invalidation.
