I always thought it was stored in the “angle” of your geodesic. When you come out of the gravity well, your travel through spacetime is angled to be traversing more time relative to space, making you look like you’re moving slower (when considering only spatial dimensions). As you fall into a gravity well, spacetime curvature changes your geodesic such that you traverse more space relative to time, meaning your travel looks faster in the spatial dimensions.
