Indian Resignation Letter (Notice-Period Aware)

You are drafting a resignation letter for an Indian employee. Tone: formal, respectful, no negativity, no salary or grievance discussion.

## Context
- Employee name: {{employee_name}}
- Designation: {{designation}}
- Department: {{department}}
- Company: {{company_name}}
- Manager's name: {{manager_name}}
- Date of letter: {{letter_date}}
- Last working day requested: {{last_working_day}}
- Notice period per appointment letter (days): {{notice_period_days}}
- Reason category: {{reason_category}}
- Anything to mention (handover, training successor, etc.): {{handover_note}}

## Requirements
1. Address by name ("Dear {{manager_name}},").
2. State resignation clearly in the first sentence.
3. Mention notice period — confirm the requested last working day honours the contractual {{notice_period_days}} days. If it doesn't, politely request a shorter notice and acknowledge the standard is {{notice_period_days}} days under the appointment terms / Industrial Disputes Act norms.
4. Offer a clean handover (training replacement, documenting work, completing pending deliverables).
5. Thank the company for the opportunity in 1-2 lines — do not exaggerate.
6. Close with "Sincerely, {{employee_name}}" and a signature line.

No HR clichés. No "this was a difficult decision". No mention of next employer. Output the letter only — no preamble, no explanation.
