Nebula page policy

Author active Workbench page previews in the top-level pages/ directory.

Nebula may also keep reference examples in examples/pages/, but those are examples only and should not replace the canonical Workbench pages directory.

If the repository includes examples/pages/, use those files as reference input when authoring real Workbench pages in pages/.

Only pages in the canonical pages/ directory are valid local verification targets in this repository. After creating or visually modifying a page, use nebula-component-validation to run repo-local static validation.

Use canvas-page-definition for the generic page-spec contract, and canvas-workbench/references/pages.md for the Workbench-specific page preview flow.
