# Build addon.zip for torttube — runs from a host with SSH access to the build host.
#
# Cross-compiles the sidecar via messense/rust-musl-cross:aarch64-musl
# (one-shot container, no host-toolchain mutation), bundles yt-dlp's
# aarch64 release binary, packages with the Kodi addon dir layout, and
# drops the zip at /srv/downloads/torttube/ on the build host.
#
# Usage: bash scripts/build-addon-zip.sh
#
# Expected: ssh alias "build-host" works (per your SSH config), and the
# torttube source is at /build/torttube/
# on the build host (rsync first if you're iterating locally).
