022 router fmt blk

// PINS: fmt.blk inside an orisha:router arm, after a bare-return bind.
// Ward's GET / is `info(): i |> fmt.blk { … {{ i.processor_name:s }} … }`.
// 350_021 pins the bind with ln; 620_007 pins fmt.blk at top level; neither
// is this combination. The template is HTML: `<h1>{{ … }}` contains the
// substring `>{`, which is also typed-source syntax (`event <Type>{`).
// That scan must not steal the source-opening `{` from `fmt.blk {`.
// The formatted string is the response body.
