Mobile Overlay Rules

Use three overlay buckets on mobile:

1. Keep compact alerts for short confirm or cancel decisions with no meaningful input.
2. Use responsive bottom sheets for pickers, selectors, and lightweight forms with stable bottom actions when confirmation is required.
3. Use full-height mobile overlays for longer forms, typed confirmations, file handling, or device-heavy tasks.

Implementation rules:

• Use ResponsiveDialog for non-destructive editing and selection flows.
• Use mobileVariant="sheet" for tall bottom sheets.
• Use mobileVariant="full-height" for longer mobile tasks.
• Keep AlertDialog separate for desktop destructive confirmations.
• Do not convert immersive media or scanner experiences into shallow sheets.
