Creative brief for a project

Write a creative brief for {{project: e.g. redesigning the landing page for a B2B analytics product}}.

Project context:
- Client / stakeholder: {{name or "internal"}}
- Budget: {{amount or range, or "TBD"}}
- Timeline: {{deadline or sprint length}}

Structure the brief as:

1. **Project overview** — one paragraph: what's being made, why, for whom
2. **Business objective** — the measurable thing this creative work needs to move
3. **Target audience** — specific enough to be useful (not "companies" — "mid-market RevOps managers at Series B SaaS companies")
4. **Key message** — the single idea the audience should leave with
5. **Supporting messages** — 2–3 proofs or context points that back the key message
6. **Competitive context** — what 2–3 comparable things look like, and where the whitespace is
7. **Mandatory elements** — legal, brand, format requirements that constrain the work
8. **Tone and feel** — 3–5 adjectives, each with a one-line description (e.g. "warm — feels like a recommendation from someone who knows the work, not a press release")
9. **Deliverables** — exact outputs, file specs, dimensions if relevant
10. **Success metrics** — how you'll know the work succeeded

Hard rules:
- No "synergy," "innovative," or "cutting-edge" in tone descriptions
- If budget and scope are mismatched, flag it before writing the brief
- If the success metric can't be measured, rewrite it until it can be
