# PR-time smoke for the Tauri desktop wrapper. Builds the frontend and the
# Tauri Linux debug binary, with no codesigning. Catches:
#   - tauri.conf.json drift
#   - src-tauri Cargo.toml or rust source breakage
#   - Tauri CLI version drift (we pin 2.10.1, matching release-desktop.yml)
#   - frontend output not picked up by Tauri's distDir
#
# Linux-only on a free `ubuntu-latest` runner. Mac and Windows desktop builds
# stay in release-desktop.yml (manual `workflow_dispatch`) because they need
# code-signing secrets and ~30 min of runner time each.
