+- Mockup sample version 3 contains three different playable genres and trajectories: stable social/collection Willow's Park, declining competitive racer Orbit Racers, and discovery-surge co-op RPG/crafting Dungeon Workshop. Each has its own activity definitions, events, products, custom player fields, and personality mixture. Playstyle is visible in player columns/profile tags; Behavior is a premade column template. The fictional personality labels and acquisition-source tags are simulation metadata, not a production classification/discovery integration.

 - Overview starts with one expandable Everything at a glance analysis, replacing the Game health section header. It interprets seven-day trends versus the prior week with latest-day/weekday context, then discusses strengths, player-experience weaknesses, activity/progression friction, monetization quality, and test priorities. It uses selected evidence rather than repeating the daily/weekly metric recaps below. Matched returning-player snapshot changes can inform economy/progression observations without assuming causation.
 - Remove the Summaries workspace/mobile navigation and standalone summary UI. Existing summary-page bookmarks redirect to Overview with their game query preserved. Daily/weekly numerical reports remain below the broad analysis. Analysis stays game-specific, cached daily, and labeled as sample text.
