Windows (x64)	TBD	🚧 In Progress

Important

Chromium sandbox status: the .deb/.rpm packages and the install script enable the full Chromium sandbox automatically (SUID chrome-sandbox helper). The AppImage runs with the sandbox disabled (--no-sandbox) because AppImages cannot ship a SUID helper — prefer the packages, or extract the tarball and run sudo chown root:root chrome-sandbox && sudo chmod 4755 chrome-sandbox next to the binary. The in-progress Windows builds currently run without the Chromium sandbox (cef_sandbox.lib is not yet linked).
