Last-minute cancellation reschedule SMS

Write an SMS reply when a client cancels last-minute.

Client first name: {{first_name}}
When they were due to be seen: {{appointment}}
Reason they gave (or 'didn't say'): {{reason}}
My cancellation policy stance (let it slide / charge / case-by-case): Letting it slide this time
Reschedule options I have available: {{reschedule}}

Write 1-2 sentences. Acknowledge without judgement. Briefly note the policy if charging (one short line, not a lecture). Offer the reschedule options. Don't say 'no worries' if you ARE charging — that's mixed signals.

Return just the SMS body.
