platform-permissions

# Platform Permissions - Request permissions at point of use with a clear rationale — never a wall of prompts at first launch. - Handle every state: granted, denied, restricted, and "denied, don't ask again" (deep-link to settings with an explanation). - The feature degrades gracefully without the permission; a denial never crashes or dead-ends the flow. - Test the denied path explicitly — it is the path reviewers and stores check first.
