//! The Askama entry point for the two described git-repository removals.
//!
//! Shape 8 (`b279b9eb`), through the glue-module ruling `27d5e5b8`. Both
//! destroy an association rather than a repository, and both ask, because a
//! creator cannot tell the two apart from the button alone.
//!
//! Each prompt names what it acts on, so the two are separate calls rather than
//! one with a label parameter: the sentence differs, not just the address.
//!
//! `DELETE /api/projects/{id}/repos/{name}` and
//! `DELETE /api/repos/{id}/collaborators/{user}` are plain API routes the
//! description layer does not serve. Both answer the whole section rebuilt, so
//! the control says where that lands. See [`Action::replaces`].
//!
//! Ids arrive as `impl Display` rather than `&str`: the caller is Askama and
//! the server's ids are typed newtypes over `Uuid`, so asking for a string
//! would push a `to_string()` into every call site to say what `format!`
//! already says here.
