hf-sync: mirror front-door from GitHub 61e288ac

harden(anatomy): add CSP/HSTS/nosniff/Referrer + clean Server banner via server.py; preserve COOP/CORP; same files/port (non-breaking)

fix(space): emit COOP/CORP from the docker static server + honest README

fix(space): restore Docker wrapper to serve the static bundle (static SDK migration wedged the runtime -> 404)

remove stale Dockerfile: space is sdk:static (GitHub source carries none); resolves 404 on the static mirror

fix: re-home static Space as Docker (static hosting 404s org-wide); serve same files via python http.server on 7860
