3Box Shared Cache

A lightweight cache sharing module for 3Box that uses an iframe to share cache across domains. Version 1.1.0 is the latest stable release. It is designed specifically for the 3Box ecosystem, providing proxied storage for OrbitDB and IPFS via postMessage communication. Key differentiators: enables cross-domain cache sharing without same-origin restrictions, tightly integrated with 3box-js. The library is minimal and focused on the iframe-mediated proxy pattern.
