User and Company Feeds
Signed-in company feed and public profile timelines. Promoters post; guests see only public `/u/:slug` profiles, never internal tickets or email.
OL Edge publishes an activity timeline on each user’s public profile and a company firehose for signed-in employees. Native posts, catalog activity, and optional blog links appear as cards. Guests can open /u/:slug public profiles; the company feed stays behind sign-in.
