Storyline

# poster_onepager / storyline

## Goal

Turn the complete accepted source and poster objective into one audience, one defensible promise, and one coherent action path.

## Good Work

- Author the headline, subheadline, audience judgment, why-now, proof promise, and call to action from the real source.
- Make the headline independently meaningful without reducing the poster to a slogan or information pile.
- Preserve evidence and uncertainty appropriate to the requested action; route unsupported promises upstream.
- Let blueprint/canvas discoveries refine the smallest affected story decision while keeping approved judgments stable.

## Handoff

Return the storyline object required by the attached output contract, without fixed panel slots or sample copy.
