3/// A bounded reactive counter.
4///
5/// Constructed via `Counter::new(min, max, step)`
6/// (Lombok `New`); the counter starts at `i32::default()`
7/// (`0`). Use [`Counter::set`] (or one of the mutator
8/// methods) to set the initial value. The current value
9/// is exposed as a `Signal<i32>` accessed through
10/// `get_value()`. Mutators (`increment`, `decrement`,
11/// `set`, `reset`) write through that signal, so any
12/// render closure that reads `counter.get_value().get()`
13/// re-renders when the value changes.
