Module dates 

Turning the dates a vault writes into the dates a feed reader will accept.

A vault’s frontmatter carries dates as whatever the author typed — 2026-08-16, 2026-08-16T09:30:00Z, a YAML timestamp with a space in it. That is right for a document: the grain a person wrote in is information, and prov keeps it. It is wrong for syndication, where the formats are specified and checked: Atom requires RFC 3339 and RSS 2.0 requires RFC 822 dates, and feeds carrying a bare 2026-08-16 are rejected by validators and misparsed by readers.

So this module reads the loose spelling once and writes the strict one, for each of the two grammars that need it. A date with no time of day is read as midnight UTC — the only reading available, and the one every static site generator makes.

Hand-rolled rather than chrono, because this crate must stay portable to wasm32-unknown-unknown and free of a clock: nothing here asks what time it is, it only re-spells a time it was given.
