Svelte Derived Stores: Reactive Values from Other Stores
A Svelte derived store is like a spreadsheet formula for your state. It listens to other stores and automatically computes a new value whenever they change. The footgun is trying to write to it—it's read-only; you must update its sources instead.

This automates state synchronization, like creating a `fullName` store that updates when `firstName` or `lastName` changes. The main footgun is trying to write to a derived store; you must update its source stores to trigger a recalculation.
