- Cap /feed.xml at the current America/New_York calendar day so
pre-scheduled future verses (and stray 2124 rows) can no longer
surface at the top of the feed
- Emit DST-aware RFC 822 pubDates (correct -04:00/-05:00 offset) instead
of a hardcoded EST offset, and parse calendar days as UTC so titles
no longer shift by one day on UTC hosts
- Add content-addressed ETag + Last-Modified with If-None-Match /
If-Modified-Since conditional handling
- Add atom:link rel=self, content:encoded, channel pubDate/generator/image
- Move RSS auto-discovery <link> into app.html: the root route sets
ssr=false, so the layout <svelte:head> link never reached the raw HTML
and feed readers could not discover /feed.xml
- Extract feed helpers into $lib/server/rss and add unit tests
