File	What
`lib.rs`	The router and fetch handler: routes, origin, the cached stylesheet, security headers.
`explain.rs`	The section on where Jev is used: the diagram, the topics and threshold, three real requests. Read from the code's own data; its tests hold it to that.
`view.rs`	Pages as pure functions (maud): the page, and the fragments a mood, mascot or tour change replaces (the cat, caption, stages, the mood pills with the playing one's hourglass and countdown, and the Play tour / Pause tour button). Its tests are the page's contract.
`pic.rs`	A pixel icon (`site::config::Pic`) and the icon, row-header, text table the page uses for lists of facts.
`media.rs`	`/preview/loop.mp4` with byte ranges (header logic; which bytes is `site::range`).
`headers.rs`	The Content-Security-Policy and the headers every response gets.
`log.rs`	What is logged and at which level; built only from closed types so no visitor can be in it.
`page.css`	The page's own styles, inlined after the shared sheet.
