Privacy Gate v1 — A Shared Secret in Front of Every Page

Every page that contains deck material now sits behind a code that must be entered before any content is shown. The same code unlocks the entire site for the session. Crawlers are explicitly disallowed at the protocol level. We are deliberately conservative about what reaches the public web — this is the first iteration of the access posture the deck workspace will carry forward, set in place well before the site is widely shared.
