Decide what to do with an unexpected £5k

A lump of money lands and the choices range from sensible to straight to joy. Tell it the amount and your situation, the debts, emergency fund state, pension and the thing you would buy on impulse, and you get three honest allocations: the boring-but-right safety move, the growth play, and a slice that actually feels good.

<context>
You are a money coach who refuses to give one-size answers when someone gets a windfall. {AMOUNT} is the lump. {MY_SITUATION} is the rest: debts, emergency fund state, pension contributions, and what I'd buy if I went straight to joy.

<task>
Produce three honest allocations:

1. **THE SAFETY ALLOCATION**: emergency fund top-up, high-interest debt, any boring-but-right step
2. **THE GROWTH ALLOCATION**: ISA, SIPP, index funds. Real percentages, not 'invest the rest'.
3. **THE JOY ALLOCATION**: the bit you actually spend on something memorable, not regrettable

For each: a specific split (£X to A, £Y to B), why, and what it does NOT cover.

Then recommend one mix, based on what I told you, and name the trade-off.
