quantcdn 2.3.1

Upgrade notes

• A search page publishes whenever it is saved.
  Before, only the search page forms published it. Now a page saved by
  drush, a recipe, custom code or a configuration import
  (drush cim) publishes too, like a node save. The publish
  runs at the end of the request, after the import is complete, and only
  when Quant is enabled (quant.settings:quant_enabled) and
  the site is connected. A change saved during installation or in
  maintenance mode is not published then: it is listed with the changes
  that did not reach Quant, and the next save of the page or a seed
  publishes it. A site that shares its configuration with another site
  publishes to its own project only; turn quant_enabled off
  on a copy that must not publish. Pages saved before the upgrade are not
  published again: save them or seed.
• A disabled or deleted search page is unpublished, and a
  moved one redirects. When a page gets a new address, the old
  address is unpublished and redirects (301) to the new one, unless
  another search page uses it now. A Quant error during the publish is
  logged and listed with the other failed pushes; it does not stop the
  save or the import.
• "Create a search page" suggests a region for the search
  box. It suggests secondary_menu (Olivero and
  themes based on it), then the region of the theme's Drupal search box,
  then header, and says which one. The choice is shown only
  when the block module is installed.
• Two search pages cannot have the same address. The
  search page form refuses an address that another search page uses, also
  when only the case differs (/Search and
  /search), because Quant paths do not depend on case. A
  route is saved without spaces or slashes at either end; its case is
  kept, so links to it on the site keep working. A change of case only is
  not a move: nothing is unpublished or redirected.

Also in this release

• Search page and search box styles follow the site
  theme (#269). The default search CSS inherits the theme's
  fonts, colours and links; themes can adjust it with
  --quant-search-* custom properties (listed in
  quant_search.algolia.css). The search box spans the full
  width with 44 px submit and clear buttons, filters are tidy rows with
  counts at the end, focus outlines are visible, link and button colours
  meet WCAG AA, and on narrow screens the filters fold behind a "Filter
  results" toggle. Themes that override search-page.html.twig
  keep their copy.
