Captions Overlay Doctrine
Overlay doctrine — supplements the upstream
embedded-captionsskill. Applies ON TOP of it; do not expect it folded into the upstream skill.
Two ideas combine here. First, the caption model — every spoken phrase is drop,
rail, or embed, and embed is the scarce earned peak, not the default. Second, the
overlay law — a caption line is composited ON TOP of the film as an overlay; it is
NOT a reserved zone, so you never shift content up or leave a dead band to "make room"
for it. The two reinforce each other: because captions ride as an overlay (the verbatim
rail in front, the occasional embed behind the subject), the composition keeps its full
frame and centers on the true vertical center.
