/* Melon Lite Style - Elegant Dark & Green Theme */
/* Maintenance map:
   - style.css owns base tokens, global layout, common components, and page-level UI.
   - floating-player.css is loaded later and owns late responsive/player overrides.
   - Prefer editing the nearest named section instead of appending broad overrides.
   - Keep new selectors scoped to a page class or component root to avoid regressions.
