# =============================================================================
# Prepare a Linux Mint / Debian / Ubuntu x86_64 host as a full WarzonePhone
# Android build environment. Installs everything the docker wzp-android-builder
# image has, but directly on the host — so we can iterate locally without
# docker layer caching, see real linker output, run gdbserver, etc.
#
# Target host: root@172.16.81.192 (Linux Mint on the LAN)
#
# Usage (from the macOS workstation):
#   scp scripts/prep-linux-mint.sh root@172.16.81.192:/tmp/
#   ssh root@172.16.81.192 'nohup bash /tmp/prep-linux-mint.sh > /var/log/wzp-prep.log 2>&1 &'
#
# The script is idempotent: safe to re-run if a step fails. Each stage tests
# for its target before doing work. Progress + completion is pinged to
# ntfy.sh/wzp so we can track it from the phone.
#
# On success the host has:
#   - JDK 17
#   - Android SDK (cmdline-tools + platforms 34/36, build-tools 34/35, NDK 26.1)
#   - Node.js 20 LTS + npm
#   - Rust stable + aarch64/armv7/i686/x86_64 android targets
#   - cargo-ndk + cargo tauri-cli 2.x
#   - /opt/wzp/warzonePhone  (cloned workspace checkout on feat/desktop-audio-rewrite)
#
# Everything lives under /opt/android-sdk and /opt/wzp so nothing leaks into $HOME.
