# MASS figure provenance

The website uses original figures and qualitative results from the MASS
project. The display assets preserve the source content; resizing and WebP
encoding are used only to keep the page responsive and fast.

The comparison slider shows one held-out qualitative episode, not an aggregate
test result. Both sides use the same episode, viewpoint, action sequence, and
rollout tick.
