# Tauri desktop (Linux) build — SEPARATE from ci.yml on purpose: this is a heavy
# Rust + AppImage build (~20-40 min) that should NOT run on backend/frontend-only
# pushes. Scoped to desktop/** (+ this file). Produces the .deb and .AppImage.
#
# Toolchain comes from the ci-tauri image (Rust + Node + WebKitGTK 4.1 + tauri-cli);
# runs-on is just a registered scheduling label (Label Model B), not a per-purpose
# runner. The frontend is built here because tauri's generate_context! embeds it.
