Rating & Gamification:

Layout & UI Refinements:

• Move "Associated Diving Centers" to the sidebar to optimize space.
• Create a "Top Bar" for breadcrumbs and action buttons (Share/Edit).

• Standardize depth icons to TrendingUp across all detail views.
• Standardize all action buttons using the new Button component.

Security & Stability:
