# desktop-prod.sh — Build & launch OmniVoice Studio as a "fresh install"
#
# This gives you the EXACT same experience as a user downloading the
# installer (DMG on macOS, AppImage on Linux):
#   • Full Rust bootstrap (venv creation, uv sync, model setup)
#   • Splash screen with live logs
#   • Region selector, version badge, etc.
#
# Usage:
#   bun desktop-prod          # build debug + wipe + launch
#   bun desktop-prod:run      # re-launch last build (skip compile)
#   bun desktop-prod:upgrade  # rebuild, but keep data (test upgrade)
