+Feed polish
+===========
+
+A Pelican plugin that fixes two things in the generated Atom/RSS feeds, both
+from the "RSS Feed Best Practices" checklist (kevincox.ca, 2022):
+
+* **Absolute URLs in entry content.** Posts link to each other with relative
+  hrefs (``iam-safe-defaults-fail-loud.html``, ``/tools/iam-blast-radius/``).
+  That is fine on the site, but many feed readers resolve relative URLs in
+  feed content wrongly (or not at all), so the links break in the reader. Every
+  relative ``href``/``src`` in an entry's content and summary is resolved
+  against the entry's own permalink. Fragments (``#x``), ``mailto:``,
+  ``tel:`` and ``data:`` URLs are left alone.
+* **Feed title.** Pelican always titles feeds with ``SITENAME`` (the long
+  ``<title>`` used for SEO). ``FEED_TITLE``, when set, replaces that prefix in
+  feed titles only, keeping Pelican's `` - <category>`` suffix on category feeds.
+
+Runs on the ``feed_generated`` signal, so it only touches feeds, never the site
+pages.
