(Forward — the broader spatial/dimensional potential of the Doa Doa no Mi is leveraged again in Blueno’s later CP9 fights and awakening discussion. Conservative: this is an on-page mechanic, queued as a Foreshadowing seed only for its forward-payoff in Blueno’s later combat. Mark status: confirmed + set payoff_chapter when synthesized.)

Why this matters
A prop-tell + chekhov-explicit: a Devil-Fruit power’s scope is quietly expanded on-page (walls → the open air itself) in a throwaway escape beat, pre-loading the fruit’s later, larger spatial applications. Cross-link Doa Doa no Mi, Blueno, CP9.
