and POST /api/jobs. Web UI live-polls job progress.

+# Android organizer app
+
+Share a photo into **live.f12** (or pick from the gallery). The app resizes
+to JPEG, longest edge 2000px, uploads to `POST /api/jobs`, then polls until
+the worker is done. Variants and intermediates land in
+`Pictures/livef12/{job_id}/`. A local notification fires when the job
+finishes — no ntfy, no Play Services.
+
+## Build
+
+JDK 17, Android SDK 35. On this machine:
+
+```bash
+export JAVA_HOME=/usr/lib/jvm/java-17-openjdk
+export ANDROID_HOME=$HOME/Android/Sdk
+cd android
+./gradlew assembleDebug
+adb install -r app/build/outputs/apk/debug/app-debug.apk
+```
+
+First launch: Settings → paste the `UPLOAD_TOKEN` from the server `.env`.
+Default server URL is `https://live.f12.rocks`.
+
+## Share target
+
+Android share sheet → live.f12. That's the replacement for dropping a
+file into a Syncthing folder.

+#   Gradle start up script for POSIX generated by Gradle.
+#
+#   Important for running:
+#
+#   (1) You need a POSIX-compliant shell to run this script. If your /bin/sh is
+#       noncompliant, but you have some other compliant shell such as ksh or
+#       bash, then to run this script, type that shell name before the whole
+#       command line, like:
+#
+#           ksh Gradle
+#
+#       Busybox and similar reduced shells will NOT work, because this script
+#       requires all of these POSIX shell features:
+#         * functions;
+#         * expansions «$var», «${var}», «${var:-default}», «${var+SET}»,
+#           «${var#prefix}», «${var%suffix}», and «$( cmd )»;
+#         * compound commands having a testable exit status, especially «case»;
+#         * various built-in commands including «command», «set», and «ulimit».
+#
+#   Important for patching:
+#
+#   (2) This script targets any POSIX shell, so it avoids extensions provided
+#       by Bash, Ksh, etc; in particular arrays are avoided.
+#
+#       The "traditional" practice of packing multiple parameters into a
+#       space-separated string is a well documented source of bugs and security
+#       problems, so this is (mostly) avoided, by progressively accumulating
+#       options in "$@", and eventually passing that to Java.
+#
