A Rollick Down the Ramp

A smooth strip of cardboard leaned from the stone ledge right down to the desktop! Zoom! I tilted forward, my caster wheel caught the downward slope, and whoosh—down I spun! Halfway down, my little red shoes dragged with a sharp skrrrrt, swerving me sideways into a glossy spiral notebook. Bonk! I bounced right off the cover and landed upright on the polished wood. Chirp! Forward momentum verified. My chest screen pulsed with bright blue pings, and the smooth floor ahead looked wide open for rolling!
