-macOS menu-bar app: hotkey region capture into a review PDF with PASS/FAIL boxes, AirDrop send, annotation-return tracking
+A macOS menu-bar app that captures a remembered screen region, builds a one-screenshot-per-page PDF, AirDrops it to an iPad for markup, then watches for the annotated file to come back.
+
+## Hotkeys
+
+- **⌥⇧1** — pick a new region, then capture it.
+- **⌥⇧2** — capture the remembered region instantly (no picker).
+
+## Screen Recording permission
+
+On first launch macOS asks once for Screen Recording. Grant it at **System Settings > Privacy & Security > Screen Recording**. You never have to do this again as long as the app is not re-signed with a different identity.
+
+The grant is bound to the bundle identifier `ai.flowmaster.shotdeck` plus the code signature. Changing either one forces a fresh prompt.
+
+## Build
+
+```bash
+swift build && swift test
+./scripts/build-app.sh          # signed .app for daily use
+open .build/Shotdeck.app
+```
