- **summary:** (handle)(frame_period_ms)(frame_count)(column_count) — loop row-major through the spritesheet. Every frame preserves draw-texture's source-rectangle width/height; frame=floor(elapsed/frame_period)%frame_count, src offset=(frame%columns*width, frame/columns*height).

- **grounding:** source=investigation, confidence=high
- **evidence:** Native /v2 decompile: worker stores period at obj+0x230, frame_count at +0x238, columns at +0x23c. Interpolator computes ((now-start)/period)%frame_count, then offsets both source-rect X bounds by rect_width*(frame%columns) and Y bounds by rect_height*(frame/columns). SC0000 uses (100,8,4) with AE001H's eight 200x200 cells in a 4x2 800x400 sheet.

Worker gfx_worker_set_srcrect_cell @0x47ed90 stores timing at obj+0x48/+0x5c, layout at +0x238/+0x23c, and target at +0x234. C# currently retains the endpoint cell immediately.
