Styling and spacing#
Color maps and text callbacks can make architecture roles visible without changing the underlying model. Keep styling deterministic in generated docs by using explicit colors/fonts/layout parameters where visual diffs matter.
SpacingDummyLayer creates a dynamic Keras-compatible placeholder used
only to introduce visual separation. It imports TensorFlow when instantiated.
Do not add spacing layers to a production computational graph merely to obtain a
nicer documentation image; build a visualization-specific representation when
possible.
