//! The Askama entry point for the described "remove this link" button.
//!
//! Shape 8 (`b279b9eb`), through the glue-module ruling `27d5e5b8`. One of the
//! two sites the shape recorded as unsayable: the template reached its row with
//! `hx-target="closest .link-row"`, and naming a region cannot say a relative
//! selector.
//!
//! [`Action::replacing_enclosing`] is that sentence in a spelling every
//! renderer reads, and it takes no parameter because the act is inside the row
//! it removes. The row says `data-row` in Askama, which is the attribute a
//! described row already carries and the one the target selects on. Nothing is
//! invented: the class stays where the page's own scripts still read it.
//!
//! `DELETE /api/links/{id}` is a plain API route the description layer does not
//! serve, which is why the control names what it replaces at all. See
//! [`Action::replaces`].
//!
//! # Why the caller wraps this in a span
//!
//! `link_remove_btn` was never styling. `static/tab-user-profile.js` hides the
//! Remove while a row is being edited and finds it by that class, and a
//! described act carries the class every described act carries. The class moves
//! to the element around the control, which is where a fact about that page
//! belongs and what `export_act` already does with its layout classes. It goes
//! when the profile tab is described and the edit flow with it.
//!
//! 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.
