"""Does a citizen's turn report tell them the number of points they will have?

`actions.ap_budget_of` is the world's answer: the *smaller* of the standing
budget and the newcomer allowance, for the batches inside the landing window.
`reports.build` reads `players.ap_budget` — the standing budget alone — and
prints it under "N action points next turn".

    cd research/hesper/pr4-review && python report_ap_header.py

Found while reviewing PR #4, which corrected the same class of claim in the
upkeep notice. This one is older and is not the PR's.
