Project notes

This is a Deno project. Use Deno tasks and Deno-compatible tooling for CLI and shared-code work.

When revising HTML that was already shared, retain its existing URL. Untargeted nzip site push reuses a unique breadcrumb for the same logical source; pass the prior target explicitly when the source has multiple matches. Use --new only when a separate share was requested. Use site push for content and site policy for TTL/password changes.
