Emberstage v0.1.0-beta.5

Download your installer from Assets below: Emberstage-Setup.exe (Windows), Emberstage-macOS.dmg (macOS), or Emberstage-Linux.tar.gz (Linux), plus its matching .sha256 checksum. Do not choose the automatic Source code archives for normal installation. Follow the platform installation instructions with OBS closed, then use the operator guide. Unsigned preview: macOS requires Python 3 and is not notarized. Linux requires Python 3 and supports native and Flatpak OBS via a host-side installer. CI fixture/package checks do not replace OBS hardware and live-output rehearsal.
