kaptein-viewmodel

The renderer-agnostic domain layer — the product. It owns all semantics: columns, sorting, filtering, status inference (including view-definition/lens evaluation), permission decisions, and action graphs.

Frontends (TUI, GUI, headless, serve) consume the render contract defined here and own only geometry. This crate is wasm-pure.
