The one-page structure
Object — what physically gets delivered. Audience — who sees it and where. Constraint — the thing that cannot change. Date — the real one. References — two you like, one you do not, with a sentence on why.
Why the "one you do not like" matters
Positive references narrow the field slowly. A negative reference narrows it instantly. "Not this, because the type feels corporate" tells us more than five moodboards.
Example
> Object: single cover art plus a square animated loop. > Audience: streaming listeners, mostly mobile. > Constraint: the artist's face cannot appear. > Date: master delivered 14 March, art needed 1 March. > References: two links liked for texture, one disliked for being too clean.
What not to include
Full page counts of background history. Send it if we ask, but the first brief should fit on a screen.
