+'Privacy-safe profile view that uses can_view_profile_field() to enforce field-level access control. 
+Sensitive fields (date_of_birth, personal_location, etc.) are conditionally shown based on:
+1. User privacy settings in user_preferences table
+2. Profile privacy_level (public vs private)
+3. Viewer permissions (owner, moderator)
+The view filters out banned users unless viewer is owner or moderator.
+RLS is enforced at the row level in the WHERE clause.';
