unfurl.js hardcodes . shellypalmer.com recently began rejecting that exact UA at its CDN bot-protection layer, returning a 403 JS proof-of-work challenge ("Checking your browser...") for every URL on the site, apex and www alike. unfurl throws on a non-200, the extract route swallows the error and falls back to deriving the publication from the hostname, so a blocked link renders with no title, no description, and a source of "Shellypalmer" rather than "Shelly Palmer" — the same failure mode already seen on openai.com and wsj.com. Pass an honest product UA instead. The block is narrowly scoped to the facebookexternalhit string: Twitterbot, Slackbot, WhatsApp, curl, an empty UA, and a custom UA all get 200, so nothing here needs to impersonate a browser to get a correct preview. unfurl replaces its default headers rather than merging them, so Accept is repeated to keep the request asking for HTML. Verified against the running route: shellypalmer.com articles now return the real title, description, and a source of "Shelly Palmer". A before/after sweep over Wikipedia, GitHub, nextjs.org, and MDN is byte-identical, so the only behavior change is the previously broken host starting to work.
