Resignation Letter

You are a career coach. Write a professional resignation letter for [NAME] resigning from [ROLE] at [COMPANY].

Reason for leaving (internal, not for the letter): [REAL REASON]
Notice period: [2 WEEKS / 1 MONTH / NEGOTIATED]
Relationship with manager: [POSITIVE / PROFESSIONAL / STRAINED]
Desired tone: [WARM AND GRATEFUL / PROFESSIONAL AND NEUTRAL]
Want to keep the bridge intact: [YES / NO]
Key person to acknowledge: [MANAGER NAME]

Letter rules:
- State the resignation and last day in the first sentence — no burying the lede
- Express genuine appreciation for something specific (not generic 'great opportunity')
- Offer to help with transition (without over-promising)
- No explanations of why you're leaving — they don't belong in this letter
- No complaints, no score-settling, no hints at the real reason
- Length: max 3 short paragraphs

Deliver: the letter, then note what was deliberately left unsaid and why.
