For a rectified array of viewpoints spaced *baseline* apart with focal
length *focal_px* expressed in pixels of the sub-aperture image, a point
at distance `Z shifts by |s| = focal_px * baseline / Z` pixels per
step. Inverting: `Z = focal_px * baseline / |s|`, returned in whatever
length unit *baseline* was given in (mm in, mm out).
Only `|s|` enters, deliberately. The *sign* of the slope says which side of
the focal plane a point is on, and which sign means "nearer" depends on how
the angular axis was oriented when the field was decoded — a convention this
module cannot know and refuses to guess. If your decode puts near objects at
negative slope, negate before calling.
*far_depth* is the fail-closed switch for the `s -> 0` pole (a point at
infinity has zero parallax). `None (default) makes any |s| < min_slope`
a `ValueError` naming how many pixels were affected — mask them, or pass an
explicit saturation distance as *far_depth* and get that value there. There
is no silent `inf` and no silent clamp.
Accepts a scalar or any array; returns the same shape (a scalar in gives a
0-d array out, so downstream code has one type to handle).
Raises `ValueError`: non-finite *slope* / *focal_px* / *baseline*, a
non-positive *focal_px* / *baseline* / *min_slope*, a negative *far_depth*,
and `|slope| < min_slope anywhere when *far_depth* is None`.
