- Add -local flag: web/RSS-only mode that skips Matrix login and posting,
so the web UI can be exercised against live feeds without credentials
- Add Makefile (build/local/seed/test/clean) that handles Tailwind +
go build in one shot
- Fix Guardian thumbnails: NormalizeImageURL was rewriting width=1200
onto signed i.guim.co.uk URLs, invalidating the s= signature and
returning 401. Leave signed URLs alone and pick the widest
media:content variant up front instead
- Use pete.avif as the header logo, favicon, and footer mark; drop the
unused leaf.svg
