# Interactive Area Build CLI Implementation Plan

1. Extract stage definitions, aliases, canonical ordering, and conflict validation from
   `scripts/build-area.js` into a shared CommonJS module.
2. Update `build-area.js` to consume the shared resolver without changing non-interactive semantics.
3. Add `scripts/interactive-build.js` with TTY detection, area discovery, raw-mode selection menus,
   cancellation handling, and child-process delegation to `build-area.js`.
4. Change `package.json` so `npm run build` calls the new interactive script while `build:area` remains
   unchanged.
5. Add focused Node tests for stage planning and non-TTY behavior; do not invoke Blender, QGIS, or a
   real area build in tests.
6. Run syntax checks, the focused tests, existing preflight/preview tests, and manually exercise the
   interactive flow in a TTY.
