/**
 * The concept's shared page dialogs in its one modal shell (docs/concepts/workspace/index.html `dialog#modal`:
 * `.dialog-header` > `h2#modal-title` + `×` "Close dialog", then `#modal-body`). Opening a dialog while one is open
 * swaps its content, as the concept's `dialog()` does. Closing, by ×, Escape or an action, returns focus to the
 * control that opened it.
 *
 * - "Refine this view" (a1348–1364): Source / Folder / Media / Tags, each optional per page; "Apply filters" and no
 *   mock-status note because every field is a real filter, and no "Prompt evidence" field because evidence is only
 *   known per file (D14). Clear also clears the toolbar category, as the concept's does; the page applies it.
 * - "Import & inspect" (a1483–1491): only the real operations, Inspect a local image and Scan an output folder →
 *   Rescan; no "Import portable recipes" (D15). Rescan shows its running state (aria-disabled "Rescanning…"). D55: the
 *   concept's own "Scan an output folder → Review scan" row follows as "Scan for metadata".
 * - "Review metadata scan" (a1428–1432 `scan-review`, D55): Sources and Scope in a `dl.meta-grid`, the concept's
 *   sentence, a backup `.notice` ("Back up now") and Cancel / Start scan; no sample-plan note.
 * - "Copy prompt" (a1223–1241): the select-to-copy fallback when the clipboard is unavailable (D22).
 * - One-value input (a1138 `simpleInput`): a "Category"-style field (`input#action-input`) and Cancel / a primary
 *   action; used by the Images selection bar's "Set category" (#249 D8) and the toolbar's Save view.
 * - Content (a1282–1304 `dialog(title, body)`): a page-built body such as the history's "All images for this
 *   positive" and "Repeat run" media (#249 D26); `onClose` runs once when that body leaves the shell.
 *
 * Every opener takes the page `scope`: disposing it closes and removes the shell, so a dialog never outlives its page.
