Incremental AST parsing beats full re-renders for long LLM markdown streams.
Replaces O(n²) token re-parsing with true O(n) streaming; Vercel SDK does 4K re-parses on 50KB payloads.
Under 3KB gzipped Markdown parser with typed AST for custom rendering.
Hand-coded parser beats established libraries on speed but remains alpha quality.
Append-only parsing with delta-only DOM updates solves the 'wait for complete JSON' problem cleanly.
Differential dataflow in PostgreSQL; one row insertion touches only one row of computation.
