# Pre-baked cross-compiler for Linux arm64 Tauri releases (runs on Linux amd64).
# Bakes in: amd64 cross-toolchain, arm64 multiarch dev libs, Node.js, and Rust.
# This image takes ~15 min to build but is only rebuilt when deps change.
# Rebuild when: Rust toolchain version, webkit2gtk/gtk major version, Node.js major version,
# OpenSSL major version (used via OPENSSL_STATIC=1), or Tauri CLI changes that affect
# bundler system deps.
# Tag format: rust<VER>-node<VER>
