Embedded apps must adapt to the host-provided frame and request bounded height changes through the bridge.

## What you can use now

- Design for narrow drawers, modal/workspace panels, keyboard navigation, and reduced motion.
- Test loading, empty, denied, stale, offline, and error states at each supported width.

## Current limits

- No fixed pixel viewport is guaranteed across departments or devices.

## Next step

Start with the [medOS Developer overview](/developers/platform/overview) and confirm the target hospital’s enabled contracts before production work.
