Contact-pressure proxy map: the rectified deviation from the
pseudo-reference background `dev = |v - G_sigma(v)|` is gated to the
high-deviation (contact) area -- a relative gate at `0.15 * max(dev)` plus
an absolute floor of 0.005 -- amplified by the sensitivity gain and
Gaussian-smoothed, which is the standard "indentation depth is monotone in
normal force" surrogate used when a tactile pad carries no force sensor.
`a = sensitivity (gain 1..10x), b` = smoothing radius (sigma 0.5..4.5).
Output clipped to [0,1], HxW; a flat frame yields an all-zero pressure map
(no contact, no force).
