HYPIT-RS // SVML MARKUP COMPILER & CRITICAL-PATH DAG STUDIO

Pure-Rust compiler and execution kernel for .svml (Structured Video Markup Language). Parses multi-speaker dialogue turns, <orig | spoken> phonetic overrides, || prosody pauses, and @{visual-cues} into a content-addressable SHA-256 task DAG with 61.4x faster compilation than Node.js/TypeScript.
