1//! Controller helpers — auxiliary modules imported by controllers.
2//!
3//! Helpers live in `app/helpers/` (e.g. `posts_helper.rs` with `PostsHelper`).
4//! Mark the struct with `#[helper]` and call its methods from controller actions.

6/// A controller helper type. The `#[helper]` attribute generates the implementation
7/// from the struct name (`PostsHelper` → `"posts_helper"`).
