seam-engine
Pure Rust engine for page assembly, i18n resolution, build output parsing, and JSON escaping. Single source of truth for logic shared across TS, Go, and WASM runtimes. See architecture overview.

Key Exports
| Function | Purpose |
|---|---|
render_page |

Development
- Build:
cargo build -p seam-engine - Test:
cargo test -p seam-engine
Notes
- All functions take JSON strings in and return JSON strings out for WASM compatibility
- Depends on seam-injector for template slot injection
- Consumed by engine/wasm, which exposes these functions to JS and Go runtimes
