The official price label
The client names this mode “THE ENDLESS DIVE,” with the hub line “every prompt, every depth · the original ∞” and the hub status “OPEN WATERS.”
Its lock is separate from the packs. The price label is $5, the lock title is “the ocean continues,” and the button text is “UNLOCK UNLIMITED · $5.” The pay URL is set.
The official path on the sitemap is /unlimited/classic.
“OPEN WATERS” is the hub status string. It is not the words “free.” Pages on other domains that call Unlimited free are not this $5 label.
$5 packs are separate unlocks
Movies, Sports, and Geography each have their own $5 price label and their own pay URL. Words & Language has a null pay URL. Unlimited’s $5 lock is another entry, not a bundle of those packs.
The FAQ says any unlock, for any pack, turns ads off across the whole site, and that linking a Google account brings that with you to other devices.
