Crate fret_core 

Portable, backend-agnostic core vocabulary for the Fret workspace.

This crate is intentionally dependency-light. It must remain usable by:

• core/runtime crates (fret-runtime, fret-ui),
• ecosystem crates (policy/component layers),
• and backends/runners (native + web),

without pulling in backend bindings (winit, wgpu, web-sys) or forcing an async runtime.

For module ownership and “where should this go?” guidance, see crates/fret-core/README.md.
