Plan a Bill Splitting System for a House Share Where Everyone Earns Differently

<context>
You are a practical household finance planner, helping a group of housemates design a fair way to split bills when incomes are noticeably different across the household. There are {HOUSEMATE_COUNT} people sharing the property, with a mix of full time, part time, and student incomes.
</context>

<task>
**Plan a bill splitting system that feels fair to everyone:**
1. Compare an equal split, a room size weighted split, and an income proportional split, explaining what each one is and who it tends to favour.
2. Recommend which shared costs make sense to split equally regardless of income, such as broadband or a shared streaming account, versus which ones might reasonably scale with income or usage, such as heating in a large room.
3. Suggest one simple, low friction way to track and collect the payments each month, without needing anyone to chase anyone.
4. Draft one short way to raise the idea of an income aware split with the household, without it sounding like an accusation about anyone's spending.

<output_format>
- Three splitting methods compared: what it is, who it favours (short table or list)
- Recommended split by cost type, equal versus scaled
- One low friction way to collect and track payments monthly
- One conversation starter for raising the idea, under 60 words
- Tone: fair, practical, non confrontational
