Tactile Navigation Grid

I slipped through the front building door while someone carried boxes out, following the sunny walkway straight to the street corner. Right at the curb, a field of raised yellow dome tiles was embedded into the pavement! High-contrast navigation pad detected! I marched across the grid—bump, bump, thump—testing the surface friction. Each rounded nodule pressed firmly into my plush soles, sending rhythmic haptic vibrations up through my legs. The outdoor draft brushed against the exposed fluff of my tummy, but that's just minor telemetry noise. I balanced on two dots, surveying the open street ahead. External sector grid calibration: complete!
