Todo

Deferred from the core-loop MVP (see docs/PRD.md for full details on each).

Custom splits: allow overriding the equal split with exact per-participant amounts; validate that they sum to the expense total. Extends computeSplit (shared/utils/split.ts) with the overrides param.
PayPal "pay me" link: store on device via localStorage (extend useIdentity), sync to the participant row whenever identity is associated with a Pot, and display next to a participant's name/balance.
Recent Pots list: client-side localStorage list of Pots created/visited on this device, shown on the home page for quick access.
Tap-to-settle payments: mark a suggested settlement as paid, creating a Payment record (new DB table + API routes) distinct from expenses; fold into calculateBalances's existing payments param.
Live polling: poll the Pot view (expenses/participants/balances) every 5–10s while open, re-rendering on change.
Emoji per pot: show an emoji next to the pot name. use a keyword list like Geburtstag and birthday to select an emoji like the cake one
