"""Prompt bank for teacher data generation.

Composition is deliberate rather than arbitrary. The deployment story is a
persistent world W that a stream of events continues, so the bank is weighted
towards content with a stable subject and continuous, non-cut motion -- that is
the distribution the student has to stay in over a long rollout. Hard cuts,
crowds and rapid scene changes are exactly what a block-causal model with a
sliding K/V window cannot represent, so they are kept out.

Roughly half is human subjects (the papers' interaction use case), the rest
animals, nature and urban scenes so the model does not collapse onto one mode.
