+description: HomeView inline camera flow should show a non-mirrored preview and keep the saved/uploaded image in the same orientation the user saw while shooting
+type: project
+---
+
+When fixing front-camera capture issues in `HomeView.vue`, keep the in-page preview and the final saved/uploaded image in the same non-mirrored orientation.
+
+**Why:** Users rejected flows where the live in-page preview looked mirrored or differed from the final image. The expected behavior is “what I see while shooting is what gets used.”
+
+**How to apply:** In the inline `simple-vue-camera` flow, avoid extra front-camera mirroring in either preview styling or snapshot normalization. Treat the in-page preview as the canonical orientation for `img`/`fileImg`.

+description: iOS uses inline camera first (same as Android); native fallback triggers only after inline fails. The prior "native-first on iOS" approach was reverted per product requirement.
+type: project
+---
+
+In `HomeView.vue`, the inline camera is **always attempted first** on iOS (and every other platform).  The hidden `<input type="file" capture="user">` is only activated by `switchToNativePhotoCapture()` / `enableNativePhotoCaptureFallback()` after inline capture is proven to fail.
+
+**Why:** The product requirement is "use inline camera whenever the device supports inline capture; use native device capture only when inline is not supported or fails."  iOS Safari supports `getUserMedia` since iOS 14.3, so inline-first is viable.  A prior session hard-coded `useNativePhotoCapture = computed(() => isIOSDevice || preferNativePhotoCapture.value)`, bypassing inline on iOS entirely — that line was reverted.
+
+**How to apply:** `preferNativePhotoCapture` must start `false` on all devices.  Never seed it with `isIOSDevice`.  All failure paths (`openCamera` permission denied, `camera.start()` throw, invalid snapshot blob, invalid image on submit) already call `switchToNativePhotoCapture()` which sets `preferNativePhotoCapture = true` so subsequent taps go directly to native — covering the first-tap fallback automatically.

+description: Native photo capture on iOS in HomeView should not be horizontally mirrored during normalization
+type: project
+---
+
+For `HomeView.vue`, native photo capture on iOS should not apply horizontal mirroring during image normalization.
+
+**Why:** The iOS fallback uses the native still-photo picker, and the returned photo can already be in the correct orientation. Applying the same mirror correction used for other front-camera paths flips the image incorrectly on iOS.
+
+**How to apply:** Keep platform-specific normalization for native capture. Do not assume the iOS file-input photo path behaves the same as `simple-vue-camera` snapshots or Android fallback capture.
