/**
 * Star rating input. Click or hover to set a value; supports half-star
 * increments via `step="0.5"`. Implements `ControlValueAccessor` — value
 * is `number | null` (clamped to `[0, count]`).
 *
 * Keyboard: `←` / `→` bump by `step`, `Home` / `End` jump to 0 / max.
 * Clicking the current value clears it (toggle off).
 *
 * @example
 * ```html
 * <wr-rating [(ngModel)]="score" />
 * <wr-rating [(ngModel)]="score" [count]="10" step="0.5" />
 * <wr-rating [ngModel]="4.5" [readonly]="true" />
 * ```
