"""Hand-curated baselines from Numbeo public pages.

All figures are GBP/month for a single person. Source URLs and snapshot
dates are embedded so we can re-validate. Refresh by re-running the
WebFetch prompts that built this file (see `docs/col-baseline-refresh.md`
or the conversation in 2026-05-21).

Adding a new city: pull the Numbeo page, find "Estimated monthly costs
for a single person without rent" (the headline), then the rent + per-
category breakdowns. Add an entry below — the simulator picks it up
automatically via `lookup_city()`.

Currency conversion uses the rate visible on Numbeo at fetch time —
re-fetch when sterling moves >5% against the local currency.
