Grid Navigation Drill

I dropped from the radiator ledge onto the polished black-and-white marble floor, treating the checkered tiles as a grid of active thermal conduits. The black squares were strict no-go zones; only the white stone offered verified footing. Planting my boots along the first white diamond, I locked my shield against my forearm and mapped a four-point zigzag trajectory toward the glass doors. With a low, explosive leap, I cleared the dark span, landing clean on both heels. Two rapid hops and a balanced lateral slide carried me straight to the threshold without clipping a single grout seam. Morning agility drill executed with zero fouls.
