/* Workspace stickiness: the store selection rides the URL
(?store=, the FR-003 seam), which a typed URL or new tab
drops — so, like the theme, the last explicit selection is
remembered (localStorage "cairn-store") and a bare visit
redirects to it. Until the user picks a workspace, nothing is
stored and bare URLs keep the launch store, byte-identical. A
remembered key that no longer names a populated store (the
workspace was deleted) is NOT redirected to — that would poison
every future visit with the missing-DB page — it is forgotten and
the launch store serves; the valid key set rides this tag's
data-valid-stores attribute, server-rendered from the same
enumerate_stores rows the selector lists. */
