Map animation offset-shift hypothesis

Classes: offset-shift-unproven: 1, rectangular-offset-plausible: 1, row-offset-or-row-cycle-plausible: 3

This page tests an alternate offset-shift hypothesis for layer1 0x40 map animation.
It does not prove runtime tile replacement. The EXE-grounded consumer still shows 0x40 as dirty redraw and palette paths are still real.
A candidate here means the current source footprint has same-size or same-row visual neighbors that could be selected by an offset.
Use this with map_review tile selection to manually compare the map cell and source tileset positions.
