import Observation

/// An observable view‑model that drives a numeric badge.

/// `BadgeModel` keeps track of the current count (`number`) and the
/// badge’s visual appearance (`style`).  It also exposes two derived
/// properties that make it easy to bind the model to SwiftUI controls:
///
/// * `slider` – Bridges the `Int`‐based `number` to floating‑point
///   controls such as `Slider`.
