A documentation search-results page: everything downstream of a submitted
{% templatetag openblock %} bw_search {% templatetag closeblock %} query
(icvoss/django-brickwork#411, carrying the asks closed under #261).

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

What your view must supply:
    crumbs                   breadcrumb trail: [{label, url}, ...], last unlinked
    docs_nav_items           this section's nav tree
    docs_nav_active          which rail item is current
    docs_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, section} dicts, or ()
    results_state            "ready" | "empty_query" | "empty_results" | "error"
The copy below is typed 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: echo the query, list matches, and distinguish "nothing typed" from
"typed but nothing matched" from "the search backend failed". Conflating the
two empties is the standard defect #261 named.

RESULT ROWS ARE FAMILY-NEUTRAL CARDS, not .bw-listing-list__item. That listing
class is marketing-family (tests/test_family_boundary.py); using it on the docs
shell would fail the gate. Each result is an interactive bordered bw-card whose
whole surface is the link, matching the docs home start-here cards.

GROUPING: results are listed flat with the section name as muted text on each
card. A consumer who wants section headings above groups can wrap the loop;
this page keeps one list so the empty/error branches stay simple.

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 docs home.
  "error": the search backend failed. bw_alert danger.
  LOADING: not applicable for the default server-rendered path. A consumer
    who fetches results over htmx adds a loading band in their own copy.
Accessibility: query echo is visible text, not colour alone. Result cards are
  real <a> elements. Empty and error keep search + breadcrumbs landmarks.
Responsive: inherits docs shell; bw-band-grid is not used (results are a
  single column of cards so snippets stay readable).
