-- Module:AchievementSystem
-- Achievement system that loads data from MediaWiki:AchievementData.json.
-- STYLING NOTE: All achievement styling is defined in CSS/Templates.css, not in the JSON.
-- This module only assigns CSS classes based on achievement IDs in the format:
--   .person-template .template-title.achievement-{id}::after {}
--
-- The module does not use any styling information from the JSON data structure.
