// AGENTS.md §7 message card + §34 MessageItem shape.
//
// `export enum Priority` and `export struct MessageItem` are the single source
// of truth for the message domain; Slint generates matching Rust types under
// the same names (used by `src/models.rs::mock_messages`). C2 wires them
// into `ui/message-list.slint`; C3+ leaves the card body untouched but may
// adjust the trailing "open-link" button copy.

// Slint does not support `Option<String>`; the URL field is split into a
// presence flag and the string itself. `has_click_url: false` + empty
// `click_url` means "no link", exactly mirroring Rust's `Option<String>`.
