/**
 * The page-metadata field set for the Puck root config.
 *
 * Values live at `root.props._meta` in the page snapshot — branch-scoped,
 * versioned and autosaved like any other authored content. The stored shape is
 * defined alongside these fields, so the editor fields that write it are
 * versioned with it: a field set copied into a project could not follow the
 * shape as it evolved.
 *
 * The built-in field set is fixed: no admin-defined fields, no template or site
 * tiers. Fields are declared flat inside one `_meta` object field — grouping
 * them would nest object fields, deepening the prop paths the root-prop
 * migration applier has to handle. A site is free to merge its own field onto
 * the returned group; it templates like the rest and reaches `<head>` through
 * the renderer's `transform`.
 */
/**
 * The `_meta` field for a root config's `fields`.
 *
 * Pass the live root props from `resolveFields` to show what an empty field
 * will inherit, as a placeholder. It has to be a placeholder and not a value:
 * autosave persists the whole snapshot, so a derived value written into the
 * field would be saved and the field would stop inheriting for good. Reading
 * the source from root props is what makes it track edits — the fields slice
 * subscribes to the root node, so changing the title re-resolves.
 *
 * The chains mirror what the head tags actually emit: `twitter:title` from
 * `og:title` before `title`, `twitter:image` from `og:image`. A placeholder
 * that disagreed with the rendered tag would be worse than none. The site
 * default tier cannot be shown this way, since it does not live in root props.
 *
 * No `defaultProps` companion: an unset field falls back at render time, and a
 * default here would freeze boilerplate metadata into every new page.
