How a salience module decides where in a view is worth looking.

Mirrors tbp/monty/frameworks/models/salience/strategies/protocol.py::SalienceStrategy, a Protocol in Monty so a config can name any callable. It is a behaviour here: a strategy answers a salience map of the same shape as the depth image — one number per pixel saying how interesting that pixel is.

The Monty.Context comes with the images because a strategy may sample — a random walk over candidate locations does — and anything that samples has to be reproducible from the episode seed (docs/monty-differences.md §2.1).
