Refined rollout · 101 sizes × 3 variants (V1 dynamic geo · V2 dynamic
· Fallback static backup). Previews are scaled and stream in a few at a time;
click “Open” for actual size. The dynamic panel applies test data via URL params (V1/V2).
OOH state map: there is no Mid state, and V1/V2 display the Fallback execution when the
level is Low — each dynamic banner bundles the static Fallback in ./fallback/
and swaps to it on ?tracker=Low. Set Tracker to Low below to see it.
