Speculative closure parsing keeps LLM streams off the main thread while React melts.

Strengths

•Incremental parser re-parses only the active tail, keeping wire deltas O(n) even for giant blocks.
•Opt-in structured data channel exposes tables and lists as typed objects, skipping HTML re-parsing entirely.
•Single Rust core compiles to WASM, React Native, Swift, and Kotlin with byte-identical JSON output.

Weaknesses

•Native mobile bindings are marked experimental, limiting immediate adoption for cross-platform teams.
•Zero dependencies is great, but debugging WASM binaries in production can be opaque without sourcemaps.
