Binary self-rotation
$begingroup$
Given a binary 3D array, for each layer, cyclically rotate up each of its columns as many steps as indicated by the binary encoding of the columns of the layer above it, and then cyclically rotate left each of its rows as many steps as indicated by the binary encoding of the rows of the layer below it.
There will always be at least three layers. The top layer's columns and the bottom layer's rows should not be rotated.
Walk-through
Lets start with the small 4-layer, 2-row, 3-column array:
[[[1,0,1],
[1,0,0]],
[[1,0,1],
[0,1,1]],
[[0,1,1],
[1,1,1]],
[[1,1,0],
[1,1,1]]]
The first step is evaluating the numbers encoded in binary by the columns and rows of each layer:
3 0 2
5 [[[1,0,1],
4 [1,0,0]],
2 1 3
5 [[1,0,1],
3 [0,1,1]],
1 3 3
3 [[0,1,1],
7 [1,1,1]],
3 3 1
6 [[1,1,0],
7 [1,1,1]]]
The first layer, [[1,0,1],[1,0,0]]
will not have its columns rotated, but its rows will be cyclically rotated left 5 steps and 3 step respectively, thus becoming [[1,1,0],[1,0,0]]
.
The second layer, [[1,0,1],[0,1,1]]
, will have its columns cyclically rotated up 3, 0, and 2 steps respectively, giving [[0,0,1],[1,1,1]]
, and then the rows are cyclically rotated left 3 and 7 steps respectively, with no visible change.
The third layer, [[0,1,1],[1,1,1]]
rotated up 2, 1, and 3 steps stays the same, and neither does rotating left 6 and 7 steps do anything.
Finally, the fourth layer, [[1,1,0],[1,1,1]]
rotated up 1, 3, and 3 steps is [[1,1,1],[1,1,0]]
, but its rows are not rotated afterwards, as it is the last layer.
Putting all the layers together again, gives us the binary self-rotated 3D array:
[[[1,1,0],
[1,0,0]],
[[0,0,1],
[1,1,1]],
[[0,1,1],
[1,1,1]],
[[1,1,1],
[1,1,0]]]
Example cases:
[[[1,0,1],[1,0,0]],[[1,0,1],[0,1,1]],[[0,1,1],[1,1,1]],[[1,1,0],[1,1,1]]]
gives[[[1,1,0],[1,0,0]],[[0,0,1],[1,1,1]],[[0,1,1],[1,1,1]],[[1,1,1],[1,1,0]]]
[[[1]],[[1]],[[0]]]
gives[[[1]],[[1]],[[0]]]
[[[1,0,1],[1,0,1],[1,0,1]],[[0,0,1],[0,0,1],[0,0,1]],[[1,0,0],[1,0,1],[0,0,1]]]
gives[[[0,1,1],[0,1,1],[0,1,1]],[[0,1,0],[1,0,0],[0,1,0]],[[1,0,1],[1,0,1],[0,0,0]]]

If this is an answer to a challenge…
…Be sure to follow the challenge specification. However, please refrain from exploiting obvious loopholes. Answers abusing any of the standard loopholes are considered invalid. If you think a specification is unclear or underspecified, comment on the question instead.
…Try to optimize your score. For instance, answers to code-golf challenges should attempt to be as short as possible. You can always include a readable version of the code in addition to the competitive one.
Explanations of your answer make it more interesting to read and are very much encouraged.…Include a short header which indicates the language(s) of your code and its score, as defined by the challenge.
More generally…
…Please make sure to answer the question and provide sufficient detail.
…Avoid asking for help, clarification or responding to other answers (use comments instead).
