New page: zebra-spaces.html — multi-party voice rooms (host, 2 co-hosts,
speakers, listeners) with persistent Ed25519 identity, password-vault
backup/restore, hand-raise → mic-invite → accept flow, and signed role
transitions enforced server-side. Pairs with the new zebra-spaces-signal
relay on cors-proxy.uncloseai.com.
Other pages (chat.html → index.html, zebra-audio.html, how-it-works.html,
host-your-own.html) refreshed because their integrity stamps rolled
today; nav links to zebra-spaces added on zebra-audio and host-your-own.
