 * `border-r` dividers — byte-identical visual contract to the release page.
 *
 * Cell taxonomy:
 *   - `<EntityMetadataValueCell>` — top: large value (`text-h4` uppercase),
 *     bottom: small label (`DM_Sans` 14px secondary). Used for Type / Status
 *     / Date.
 *   - `<EntityMetadataAuthorCell>` — `<SquareAvatar>` + name + label. Used
 *     for the Author column.
 *
 * `<EntityAuthorCard>` is the convenience composer for the common
 * "Published + Author" pair. Pass `publishedAt` to get both cells; omit it
 * to get just the Author card (single-cell mode used by surfaces with no
 * separate publication-date concept).
 *
 * Renders null when `author` is null/empty unless `renderEmptyAuthor` is set.
