This directory keeps the original-resolution source images for raster assets that are intentionally smaller at runtime. Its tree mirrors the original runtime path so a source and its generated output can be matched directly.

Applications and packages must not import files from this directory. Runtime code imports the optimized copy under apps/, packages/, or services/.

When replacing an optimized image:

update the mirrored source image here;
determine the largest rendered CSS size, including hover or animation magnification;
generate a runtime image at twice that size for Retina displays;
keep the existing runtime path and format when practical;
compare the source and runtime image at the actual UI size.

Full-window wallpapers, documentation screenshots, onboarding screenshots, recordings, and platform packaging icons remain at their original runtime resolution because their display size is not bounded like an interface icon.
