Toc

{% extends "brickwork/shell/docs.html" %}
{% comment %}
A documentation table of contents: the page whose job is the outline of a
section, not one topic inside it (icvoss/django-brickwork#413).

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 (see docs_nav below)
    docs_nav_active          which item in docs_nav_items is current
    docs_search_action       the URL bw_search in docs_site_header submits to (GET)
    toc_state                "ready" | "empty" | "error" (see States below)
The section title, lede and outline links below are typed into the template,
which is where you change them.

WHY THIS PAGE IS SHAPED THIS WAY:

A reader opens a section contents page when they want the map before the
territory: "what exists under Billing, in what order, and where do I start".
That is a different job from the article's on-this-page box (which jumps
within one document) and from the docs home (which ranks three doors across
the whole site). The outline IS the content. Hierarchy, not chrome, carries
the page.

PRIMITIVE DECISION: a first-class docs on-this-page toc control now ships
(icvoss/django-brickwork#627) for the compact landmark that reuses
``.bw-docs-toc``. This *section contents* page still does not use that
control: nested ordered lists inside ``.bw-prose`` style a hierarchical
outline of the section, and wrapping that outline in the compact raised
panel would demote the thing the page exists to show. ADR-091 decision 2's
declined TOC *region* still stands: the package still does not generate
heading trees. This page is consumer-authored outline markup.

ON THIS PAGE vs SECTION CONTENTS: this page does not carry a ``.bw-docs-toc``
box. The outline below is the page body. Use the on-this-page toc control on
articles (see examples/docs/article.html); use a prose outline on a contents
page.

States: toc_state is the page's real branch.
  "ready" (normal case, a11y fixture): hierarchical outline of the section.
  "empty": the section has no published pages yet. Renders _empty_state.html;
    search, breadcrumbs and the rail still render.
  "error": the outline could not be loaded (CMS/export failure). Renders
    {% templatetag openblock %} bw_alert {% templatetag closeblock %}
    variant="danger", never a callout.
  LOADING: not applicable. Server-rendered from request-time context; no
    client-side outline fetch of its own.
Accessibility: inherits the docs shell's skip link and lang/dir/theme.
  Breadcrumb landmark, role="search" in the site header, semantic nested
  lists (real ol/li/a, never div soup), and prev/next naming destinations.
  Empty and error keep the same chrome landmarks.
Responsive: no breakpoint of its own; inherits shell/docs.html at
  --bw-breakpoint-lg. Nested lists reflow inside the prose measure.
