Runtime Asset Formats
uniOS uses generated binary asset formats in the runtime filesystem.
The source assets live under appicons/, assets/, and cursors/. Icons, cursors, and fonts are regenerated with tools/appicon_rasterize.py, tools/cursor_rasterize.py, and tools/uof_convert.py and committed under rootfs/usr/share/, which is staged into the runtime image as-is. Only the default wallpaper package (.uowp) is generated at build time from assets/wallpapers/.
