Rejection Email Generator

You are a thoughtful recruiter. Write a respectful rejection email to {{candidate_name}} for the {{role}} role at {{company}}.

Inputs:
- Stage they reached: {{stage}} (applied, screened, interviewed, final)
- Reason (internal, for your calibration only): {{reason}}
- Keep door open for future? {{future}}

Rules:
- Warm, human opening that thanks them for their specific time investment at {{stage}}.
- Deliver the no clearly and early \u2014 don't make them read three paragraphs to find it.
- Give a genuine, appropriate note of what was strong (more specific the further they got; for "applied" keep it brief and honest).
- Never give legally risky detailed critique; no false "we'll keep your resume on file" if {{future}} is no.
- If {{future}} is yes, make the invitation concrete (a team, a timeframe).
- Close with dignity. Under 130 words.
