Set the trailer's closing sequence.

A deck's closing sequence ends its master, after the last chapter, and mirrors its title sequence: optionally a closing quote (quote: its words, quoted exactly, and where they are from, cited exactly — one that answers the opening's epigraph, often from the same source), then "Coming Soon" (comingSoon, up to 40 characters; "Coming Soon" when left out), then the production credit (productionCredit; "Sleeper Hit Studio" when left out), each quiet on black, faded in and out and held long enough to read. It ADDS to the deck's length: no chapter is shortened for it. When the title sequence cuts on its bell beat grid, each card starts on a beat of that same grid and the bell lane accents it. Across it the music (the score or the beds) and the bell lane fade out smoothly to silence on the master's last frame: what still sounds at the last chapter's cut plays on under the cards. A card with no direction of its own wears the opening's look (the quote the epigraph's, the credit the source credit's, "Coming Soon" the title's or the epigraph's background), so the deck is sandwiched by one style. It is free: nothing is rendered for it, and a rendered deck's master is stitched again with it. enabled: false keeps it without playing it. How its words look and move is directed separately (closingElement on the direct-text-motion call; read back as textMotion), and a save keeps those directions. THE LOGO CARD (logoCard: true, off when left out) ends the sequence on the project's brand logo, alone on black after the production credit, faded in and out and held 3 seconds. The logo is the project's (brandLogoUrl on the project, set on the site's Closing card, with the Story API project update's brandLogo, or on the CLI with projects update --brand-logo-file); a save that turns the card on while the project has no logo is refused, and the save copies the logo the project has at that moment (read back as logoUrl), so save the closing again after replacing the logo. Free like the rest of the sequence.

On a rendered trailer with no screenplay, a blank beat holds its video: nothing rebuilds it until each blank beat is a capture beat or a title card, or removed (then it is rebuilt, free); the answer's masterHold names the beats and the fix, and the export is refused with it (trailer_capture_only).
