A product search page: everything downstream of a submitted
{% templatetag openblock %} bw_search {% templatetag closeblock %} query
inside the app shell (icvoss/django-brickwork#404). Distinct from
docs/search-results.html, which is the documentation family's equivalent.

COPY THIS FILE into your project and edit it. It is not on the template loader
path, so you cannot extend it (ADR-056); copying is the only way to use it.

What your view must supply, and nothing else:
    search_action            the URL bw_search submits to (GET), usually this page
    query                    the submitted q= string (may be empty)
    results                  list of {title, href, snippet, kind} dicts, or ()
    results_state            "ready" | "empty_query" | "empty_results" | "error" | "loading"
    nav_items / nav_active   as in list.html
The rest of this page is content typed directly into the template.

WHY THIS PAGE IS SHAPED THIS WAY:

bw_search is only a form. This page is the contract for what happens after
submit in a product application: echo the query, list matching records, and
distinguish "nothing typed" from "typed but nothing matched" from "the search
backend failed". Conflating the two empties is the standard defect #261 named;
the docs search-results archetype closed that for documentation, and this page
closes it for the app shell.

RESULT ROWS ARE FAMILY-NEUTRAL CARDS, not .bw-listing-list__item. That listing
class is marketing-family (tests/test_family_boundary.py). Each result is an
interactive bordered bw-card whose whole surface is the link, matching the
docs search-results craft on the product shell.

SEARCH LIVES IN THE TOPBAR. The app shell's topbar_search block is the product
equivalent of the docs site header search. The page body is the results
surface; do not duplicate the form in content unless your layout needs a
second entry point.

States: results_state is the page's real branch.
  "ready": query echoed, result cards render (results may still be one item).
  "empty_query": the form was submitted with no q= (or the reader opened the
    URL bare). Prompt to type a query; not an empty-result empty state.
  "empty_results": a non-empty query returned nothing. Different copy from
    empty_query; offers clear-back to the search root.
  "error": the search backend failed. bw_alert danger.
  "loading": results are in flight (htmx swap or deferred fetch). Skeleton
    band with a polite live status; not an empty state and not an error.
Accessibility: inherits shell/app.html's skip link, sidebar/drawer nav and
  page-header region; query echo is visible text, not colour alone; result
  cards are real <a> elements; empty, error and loading keep the topbar
  search landmark. Covered by the archetype harness's full gate sweep
  (render, axe WCAG 2.2 AA, no horizontal overflow, light/dark
  distinctness, skip-link first-tab-stop with JS disabled) at every W0.1
  breakpoint, both themes.
Responsive: inherits shell/app.html's sidebar-to-drawer collapse at
  --bw-breakpoint-md (48rem). Results are a single column of cards so
  snippets stay readable; no bw-band-grid.
