Not Blockers, Just Context

These are expectations for a new framework
FAQ addresses them honestly
Positioned as "complement not replacement"
Target audience: Early adopters, design systems, shared components

Quality discussions about architecture

Success Indicators

✅ Positive technical feedback
✅ People trying the demos
✅ Questions about implementation
✅ Feature requests (not just bugs)

Potential Concerns & Responses

"Why not just use X?" → We're not replacing X! LARC complements React/Vue for shared components and design systems. It's about framework reduction, not replacement. "Another JS framework?" → It's a message bus, not a framework. Think of it as the "nervous system" for your components. Works with any framework. "Production ready?" → Yes - 426 tests passing, 0 vulnerabilities, v3.0.1 on npm. Young ecosystem (2024), but stable core. Perfect for new projects and early adopters. "Bundle size?" → Core is 3.6KB minified. We've proven 60%+ bundle reduction in real apps. See Invoice Studio demo for comparison. "Browser support?" → Chrome 90+, Firefox 88+, Safari 14+, Edge 90+. Requires ES Modules and Web Components - modern browser features.
