The `#block` def captures the envelope shape every variant in `page.corvus.block` inlines (`id`, `parent`, `afterSibling`); `#children` is a sentinel referenced by `editableAs` on ordered-children fields. Variants in `page.corvus.block` declare each editable field's primitive shape via `editableAs`; the applier materializes the field into a `page.corvus.materialized#blockProperty` using the named primitive."
