Each clip page already carried its own title, blurb, poster and
og:video — but the assets behind the tags let the unfurl down. The mp4s
were tail-indexed, so previewers in iMessage, Discord, Slack and
Facebook gave up before finding a player; the tags carried no video
dimensions, without which those same sites refuse to embed one; and the
poster was a 736x578 screenshot of the workshop chrome, cropped to
nothing by any share sheet.
deploy/clips-prep.mjs fixes the set before clips-publish.sh ships it:
a lossless faststart remux of every take, a 1200x630 card per clip cut
from the poster's first-person viewport with the title set over it (an
HTML card screenshot through the harness's chromium — ffmpeg here has
no drawtext), and the fpv frame size stamped into clips.json. The page
emits the card with its dimensions, og:video:width/height, and a Share
button that opens the phone's share sheet or copies the link.
