# Core is compiled in-process into the Tauri shell as of PR #1061; the old
# scripts/stage-core-sidecar.mjs staging step is no longer needed.

# Build the frontend in DEV mode up-front so `import.meta.env.DEV` is true
# in the bundled E2E binary. That flips `restartApp` in
# app/src/utils/tauriCommands/core.ts from the real `app.restart()`
# (which destroys the WebDriver CDP target) to a benign
# `window.location.reload()`. Without this, the identity-flip path that
# fires on every E2E login kills the chromium-driver session.
#
# We then override `beforeBuildCommand` to a no-op so Tauri does not
# clobber our dev-mode dist with a fresh prod-mode build.
