expo-screen-orientation

scored against the browser-hosted simulator contract: the real package imports cleanly and its meaningful lock state, platform masks, reads, and portrait-to-landscape event behavior match iOS across eight paired runtime stages. The simulator device frame is intentionally fixed, so the score does not claim faithful UIKit rotation.

Missing (1)

deprecated bulk listener removal and same-axis portrait-up/portrait-down event filtering lack paired runtime coverage; physical device-frame rotation and sensor-driven auto-rotation are intentionally unavailable in the fixed browser-hosted simulator and do not count as an implementation gap
