SceneLoft portable build

Run SceneLoft directly from the package. Keep all bundled files together.

Video and audio import plus MP4, WebM, and ProRes export require FFmpeg and
FFprobe. SceneLoft searches its packaged tools directory first and then the
system PATH. You can also set SCENELOFT_FFMPEG and SCENELOFT_FFPROBE to exact
executable paths.

SceneLoft requires a graphics driver supported by wgpu. On Linux, Vulkan is
preferred and OpenGL ES is available as a fallback.

Project files use the .sceneloft extension. Legacy .mottion files remain
readable.
