Angle-matched landing pages (?v=hook on the invite link)

/join/<id>?v=pocket|phone|two|graveyard swaps the hero headline and
the watch-first video to continue the curiosity hook that brought
the prospect, keeping the sponsor identity in the sub line. Tools
page: each angle card gains a "Copy matched invite link" button
(personalizes through the existing bare-domain swap); Posts 6/7
carry ?v=pocket. AI prompt knows to recommend matched links.
