Expo's fetch rejects React Native's { uri, name, type } FormData parts ("Unsupported FormDataPart
implementation"), so every upload failed. Upload an expo-file-system File instead, shrunk to 1024 px
first. The server also takes bigger photos (25 MB, sharp's default pixel limit) and logs why a
picture couldn't be read.
