# Wall+ceiling-only proximity force field ("artificial gravity" grav-plating,
# weaker than the floor's plain default gravity, which this deliberately
# leaves untouched). Ship and Ball each call this with their own
# strength/range so wall adherence and ceiling adherence can be tuned
# independently per body — see ship.gd/ball.gd. Quadratic falloff keeps a
# casual flyby near a wall almost force-free, concentrating the pull in
# roughly the last third of the range so it only bites once something is
# genuinely close to the surface.
