//! The Askama entry point for the two described promo-code deletes.
//!
//! Shape 8 (`b279b9eb`), through the glue-module ruling `27d5e5b8`. Both
//! destroy and both ask; what differs is what they act on, which is what the
//! two prompts are for.
//!
//! `DELETE /api/promo-codes{,/id}` is a plain API route the description layer
//! does not serve. It answers the whole list 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.
