Home hero: audiences never carry "live streaming" again

OP OpenVibers committed 21 Sept 2026 · 12783536f6 · 2 files, +19 −8

The model started returning audience phrases shaped "X live streaming"
(the headline is "Live streaming for {X}"), so every slogan read
"crouton connoisseurs live streaming". The prompt now states the fixed
headline and bans the words outright; the job strips the framing at
either end and drops any phrase still containing "stream"; the client
cleaner does the same so the cached batch renders correctly right away.
SLOGAN_FORMAT bumped to force a fresh batch.
