/**
 * archivedLine, the one sentence every app shows on an archived file (PEEKM-2).
 */

/**
 * The line in the comment box's place on an archived file (CommentBox's
 * `closed.reason`), in every app's words alike.
 *
 * A file archived itself says so; one archived with a file above it names the
 * closest archived one by its kind — "Unarchive the page to comment." — so a
 * person unarchives the right thing, and once it is unarchived the next one up
 * is named. Which file that is comes from interop: `archive.with` is its
 * address, and the app reads its noun.
 *
 * why: https://github.com/estiva-app/estiva-docs/blob/main/decisions/a-file-is-archived-with-the-closest-archived-file-above-it.md
