Crate wall 

Panel topology: one logical image mapped onto a wall of panels, any size, rotation or mirroring, across any number of receiving cards. Rendering yields one screen-sized framebuffer: every card on the chain receives every row and keeps the pixels inside its own window (docs/receiver-identity.md), so a receiver’s position here is the position it was provisioned with. The wire protocol is not involved here.
