E0712: The fields binding a path parameter disagree on its type

Every struct below a bracketed folder may bind its parameter with a field of its name, and those fields are one type: the URL has one segment, and urls writes it one way. The folder's _layout.vuka.html speaks first; otherwise the first field found does. Reported at a field of another type, naming the first.

Wrong

pages/orgs/[org]/_layout.vuka.html    type Layout struct{ Org int; Children ui.Node }
pages/orgs/[org]/edit.vuka.html       type Edit struct{ Org string }

Right

pages/orgs/[org]/_layout.vuka.html    type Layout struct{ Org int; Children ui.Node }
pages/orgs/[org]/edit.vuka.html       type Edit struct{ Org int }
