Regenerate the landing site's OG/social card (web/landing/public/og.webp) by rendering a temporary in-app route with the real hero WebGL aurora and screenshotting it with headless Chrome. Invoke when the user says 'regenerate the og image', 'update the og card', 'change the og screenshot/copy', '重新生成 og 图', or edits any copy/screenshot that appears on the social card.
