TODO

High Priority

• Fix WASM binary size — 1.58 MB gzip exceeds 1 MB limit. Move buildComponentJS() and JSON parsing to server-side. WASM should only expose Render(). Consider: pre-parsed slots, inline template execution, or TinyGo.
• Add WASM integration tests — No cmd/wasm/main_test.go. Need JS↔Go round-trip verification.

Medium Priority

• Performance benchmarks — Add BenchmarkRender, BenchmarkImprint, BenchmarkCompareVariants, BenchmarkLayout with varying tree depths.
• TypeScript type definitions — Add .d.ts generation alongside GenerateBundle() for Web Component consumers.
• Accessibility helpers — Layout has semantic HTML + ARIA roles but no aria-label builder, alt text helpers, or focus management nodes.
• Layout variant validation — NewLayout("XYZ") silently produces empty output. Add warning or error for invalid slot characters.

Low Priority

• Unicode/RTL edge cases — Test emoji, RTL text, zero-width characters in Text nodes.
• Deep nesting stress test — Verify performance with deeply nested Layouts and large Each[T] lists.
• Browser polyfill documentation — Document closed Shadow DOM support matrix.
• CSS scoping helper — Optional utility for responsive variant CSS targeting.
