Long-enough articles (3+ in-body h1/h2) get slug ids (python-slugify,
mirroring the editor's slugify.js) and the heading text becomes a
self-link (a.anchor) for clean link copying; {#id} always wins,
duplicates get -2/-3 suffixes, h3+ never. The implicit page title is
now injected as '# {title}' into the markdown (render(title=...)), so
it takes the same first-h1 path as an explicit one: no id, href=""
self-link scrolling to top, not counted toward the threshold. The
.body wrapper is gone — segments are direct article children — and the
editor preview swaps the whole article in one go. pagerite.js tracks
the reading position in the location hash (last tagged heading above
the viewport middle; cleared at the top, never on unscrollable pages)
and scrolls to anchors after fetch-navigation.
The first positional CLI argument (default localhost) names the site's
public hostname and its data directory under the cwd, replacing the
CWD-relative pagerite.* files. The public origin (https://<hostname>)
is now authoritative configuration instead of a value learned from
admin browsers: POST /_api/site-url, Data.site_url and the pagerite.js
reporter are removed, and page rendering, sitemap, robots.txt and
analytics own_origin all use SITE_URL consistently (localhost falls
back to the request's base URL).
