Turn a One-Off Prompt Into a Reusable Template

    Turn the working example below into a reusable prompt template.

A prompt (and, if I have it, the input and output) that worked well as a one-off:
{{example}}

Please:
1. Identify which parts are **fixed instructions** (keep them) and which parts are **specific to this one case** (turn them into placeholders).
2. Return a clean template using clearly named placeholders in double curly braces — for example `{{topic}}`, `{{audience}}`, `{{tone}}`.
3. Organize it with light structure: role and task, the inputs (placeholders), constraints, and output format.
4. List the placeholders, each with a one-line note on what it expects.

Don't invent requirements that weren't in the original — the job is to extract the pattern, not redesign it. If part of the example is doing something you can't tell is intentional, ask.
