feat(film): investor caption track over the demo
preseed/captions.module renders eleven title cards from a single zui screen
driven by the director clock: the ORIGOZERO opener under the lumen title,
lower-third product claims through the parts, the BRING YOUR OWN AGENT hero
card on the tesla scene, the agent-authorship meta card, the pre-seed ask,
and an origozero.ai end card that mounts on black after the film's fade and
holds to the end of the recording. Berkeley Mono, smoothstep fades, backing
strips for bright scenes; the screen unmounts between cards. Wired from the
scene entrypoint beside the director tick.
