Use the ADR-0047 Ctrl+]-delimited demo caption to narrate the payoff
moment of three casts with a neutral one-liner (no key names): the join
result, the relationship diagram, and the m:n junction expansion. Add a
`caption` step kind to the cast generator. Captions show at the climax
during playback and clear as the cast quits.
Advanced-mode cast running simple commands (create table, add column),
culminating in `create m:n relationship` expanding to a full junction
table, each tagged `Executing SQL:`. Recorded at height 34 so the long
m:n echo + junction structure stay fully on screen. Verified against
real app output.
