- nginx basic auth on /previz/ (login file lives on the server, mounted
from docker/auth/, see DEPLOY.md step 8); private, no-store so
Cloudflare never caches it
- Print styles for previz pages: dark, A4 landscape, one section a page;
videos print as poster frames with a link
- scripts/previz-pdf.mjs (npm run previz:pdf) prints the page to
public/previz/crowd/crowd-previz.pdf via Edge/Chrome DevTools
- "PDF" download link on the page
