An editorial series: an ordered set of articles a reader works through in
sequence (icvoss/django-brickwork#419). Fifth archetype in the Editorial and
publishing family.

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_label           rail / jump label (this page uses "In this series")
    docs_search_action       the URL bw_search in the site header submits to
    series_title             series name (page heading)
    series_description       short lede under the heading
    parts                    list of {number, title, href, snippet, status
                              ("ready"|"upcoming"), published_on?,
                              published_iso?, reading_time?}, in series order,
                              or ()
    series_state             "ready" | "empty" | "error"
The headings and static rail copy below are typed into the template.

WHY SERIES IS NOT CATEGORY OR ARCHIVE:

Category (#417) groups by topic without order. Archive (#418) is chronological
across the journal. A series is a deliberate sequence the reader is meant to
follow (part 1, then 2, then 3). Evidence: reminder-threshold deep dives are
one topic AND one dated stream, but they are also a named curriculum with a
start and a next step; category and archive cannot express "you are on part 2
of 4" without inventing order that neither archetype owns.

WHY THIS PAGE EXTENDS THE DOCS SHELL, NOT A NEW EDITORIAL SHELL:

Same deciding fact as examples/editorial/article.html and ADR-091. Family
taxonomy stays the examples/ directory.

PART ROWS ARE FAMILY-NEUTRAL CARDS. Upcoming parts are non-interactive cards
(no href) so the reader sees the planned sequence without a dead link.
Ready parts are interactive bordered cards. Number + title carry sequence;
status is stated in text ("Upcoming"), not colour alone.

States: series_state is the page's real branch.
  "ready": series header, ordered part cards, series rail.
  "empty": the series exists but has no published parts yet. Header stays;
    list band is _empty_state.html.
  "error": the content store failed. bw_alert danger.
  LOADING: not applicable for the default server-rendered path.
Accessibility: part numbers are visible text; upcoming is labelled in words;
  ready cards are real <a> elements; empty and error keep search + breadcrumbs.
Responsive: inherits the docs shell; cards stack in one column.
