embed.reddit.com only renders the /r/<sub>/comments/<id> path (verified against
reddit's embed widgets.js + curl: frame-ancestors * , no X-Frame-Options, so
iframing itself is fine). But getRedditPostEmbed built a bare
embed.reddit.com/comments/<id> for redd.it short links — which serves a 'not
found' page — and the i. host strip routed i.redd.it/*.jpg image links into the
same branch. Returning a (broken) URL also suppressed renderContent's og:url
fallback that would resolve the short link to its canonical /r/<sub>/... form.
Fix: getRedditPostEmbed returns null for any non-reddit.com host, so redd.it /
i.redd.it / v.redd.it fall through to the og:url fallback (working embed or a
normal preview card, never a blank 'not found' iframe). The reddit.com post path
is unchanged. Tests updated (22 pass).
Note: the live 'broken' symptom is mostly the deploy gap — live still runs the
old www.redditmedia.com embed code while the live CSP only allows
embed.reddit.com; deploying the current lotus branch (which emits
embed.reddit.com) resolves it.
