The toolbar units' fake DOM returned select.options as an Array, so the
toolbar's .some() call passed there while it threw in every browser
(fixed in 12228e2). options is now an indexed, iterable, frozen
HTMLOptionsCollection-like object without Array methods; against the C1
toolbar three units fail with "sort.options.some is not a function".
The units also assert that an unknown sort falls back to the first
option and that a still-listed category survives a category refresh.
- Drop the invented Refine note; every field is real (D14).
- Ignore a late close event once the shell was reopened or replaced, so
an action that opens the next dialog keeps it open.
- Dialog openers require the page scope; disposing it closes and removes
the shell unless a newer page's dialog is open. Every route change
closes the shared dialog before the next page mounts.
- Clear filters also reports category '' so the page clears the toolbar
category, as the concept does.
- The toolbar requires its scope and falls back to the first sort for an
unknown value; dialog callbacks are validated up front.

Add the concept's shared page toolbar (search.toolbar with the search
field, category filter, sort and Filters) and its dialogs in one modal
shell: "Refine this view" (Source / Folder / Media / Tags, Apply filters),
"Import & inspect" with only the real operations (Open inspector, Rescan),
and the "Copy prompt" select-to-copy fallback. The sort lists the
concept's three options first (D14); there is no Save view (D16). Every
dialog returns focus to its trigger on close or Escape.
