CreationDraft's docstring promised it owns no rules—it delegates to NewGame.validate.
But it kept a local const POOL := 3 that mirrored NewGame.SPEND_POOL, inviting
silent disagreement if the source was changed and the copy forgotten.
Delete POOL. Use NewGame.SPEND_POOL directly in points_left(), with a comment
making it clear this is the single authority. The coupling is now enforced by
code structure, not by hope.

Pure, node-free, headlessly testable. Carries a seed, not a stat block. Owns no
rules of its own: errors() delegates to NewGame.validate.
The interaction rules that make creation screens buggy are pinned by test:
changing calling clears the picks; changing race drops a pick the new race now
grants (the elf/cutpurse case); re-roll clears the spend and only the spend;
minus floors at the roll; the fourth point does not exist.
