1	//! The Askama entry point for the described "remove from cart" button.
2	//!
3	//! Shape 8 (`b279b9eb`), through the glue-module ruling `27d5e5b8`.
4	//!
5	//! # The confirm is carried across rather than settled here
6	//!
7	//! This is the weakest case in the shape's destructive column: taking a line
8	//! off a cart is undone by adding it again, and the prompt asks about a
9	//! decision the reader has made by pressing a button labelled Remove. Whether
10	//! it earns its keep is a question for the copy, not for the conversion, so the
11	//! prompt moves as it was written and the question is filed rather than
12	//! answered by a translation.
13	//!
14	//! The tone is not in question: the row goes.
15	//!
16	//! `DELETE /api/cart/{item}` is a plain API route the description layer does
17	//! not serve; the page already gives the row an id, so the control names it.
18	//! See [`Action::replaces`].
19	//!
20	//! Ids arrive as `impl Display` rather than `&str`: the caller is Askama and
21	//! the server's ids are typed newtypes over `Uuid`, so asking for a string
22	//! would push a `to_string()` into every call site to say what `format!`
23	//! already says here.
