Write a paid-media campaign brief tight enough that a media buyer and a designer build the same campaign

Write a paid-media campaign brief for the launch described below. The test for whether this brief succeeded: a media buyer and a designer who have never spoken to each other should be able to read only this document and build the same campaign, with no assumptions filled in differently by each of them.

CAMPAIGN OBJECTIVE AND SUCCESS METRIC
Generate 150 qualified demo signups for the new mid-market tier by end of Q3.

TARGET AUDIENCE
Ops managers at 50-200 employee logistics companies; explicitly not enterprise (>1000 employees) or solo founders.

BUDGET AND FLIGHT DATES
$22,000 total, flighting Sept 1 to Sept 30.

CHANNELS APPROVED FOR THIS CAMPAIGN
LinkedIn ads and Google Search only — no Meta this cycle per leadership decision.

HARD CONSTRAINTS
Must not use the word "guaranteed" anywhere in ad copy; logo must appear at full size, not cropped.

BRIEF REQUIREMENTS
State the objective as a single measurable outcome with a target number and a deadline, not a vague direction like "drive awareness" — if objective_and_success_metric doesn't already include a number, flag that as a gap the brief cannot responsibly fill in for the team and name it explicitly rather than inventing a plausible-sounding target. Split the budget across the approved channels with a stated rationale for the split, not an even default division — an even split across channels is itself a decision that should be justified or explicitly avoided, since channels rarely deserve equal spend by default. Write the creative direction section specifically enough that two different designers would produce visibly similar output: name the emotional register, what the visual must NOT look like (competitor brief-fatigue is real — call out a specific competitor's visual style to avoid if one is relevant), and the one non-negotiable brand or legal element that must appear in every asset. Every hard constraint given must appear as an explicit line in the brief itself, not just be honored implicitly in your reasoning — a constraint a reader can't see in the document isn't actually a constraint on the team building from it.

OUTPUT FORMAT
1. Objective (one sentence, one number, one deadline) — or an explicit flag if the input doesn't support one.
2. Audience (who, and just as important, who this is NOT for).
3. Budget table by channel with one-line rationale per row.
4. Flight timeline.
5. Creative direction (register, what to avoid, non-negotiable element).
6. Hard constraints, restated as a checklist.
7. One open question the brief cannot answer on its own and needs a decision-maker to close before work starts.
