v0.13.92: v0.13.92

@newsroom.writer: two articles and four demonstration sites. Websites you own: a reply to an infographic that sells AI-built websites by the month, section by section with its crops, and the one-off model where the client owns the AI account, GitHub Pages and the domain. Inside Kitewing Websites: a made-up studio and three made-up client sites (a potter's catalogue, a community garden, a plumber's guides library), each a single-file vault app with its data in JSON, served under /demos/vaults/kitewing-websites/ as previews; the four sgit vaults are created and committed locally, not yet pushed. Figures, section summaries and graphs.
