Transforming data to and from storage areas using Svelte custom stores
summary
Custom Svelte stores implement the store contract (subscribe and set), initialize from and write back to localStorage sync, and apply arrays of read/write transforms so objects use JSON stringify/parse on save/load. Transforms chain so you can add LZString compression to compress strings before storage while the $store binding and API stay the same. Multiple assignments trigger multiple set calls, so prefer a single assignment or debounce in the store; you can swap localStorage for an HTTP endpoint.
