/**
 * Call Dialpad Component
 *
 * Wrapper around `sw-dialpad` that integrates with a Call.
 * When a call is connected, digit presses send DTMF tones.
 * When no call is active, the dial event bubbles up for the parent to handle.
 *
 * Input precedence (most specific wins): `.call` > context.
 *
 * @example
 * ```html
 * <sw-call-dialpad></sw-call-dialpad>
 * <sw-call-dialpad .call=${call}></sw-call-dialpad>
 * <sw-call-dialpad show-call-button @sw-dial=${onDial}></sw-call-dialpad>
 * ```
 *
 * @csspart container    - Outer dialpad container.
 * @csspart display      - Number / text display field.
 * @csspart keypad       - Grid of digit keys.
 * @csspart key          - Individual digit button.
 * @csspart key-pressed  - Digit button while pressed.
 * @csspart call-button  - The call button (when `show-call-button`).
 *
 * @fires sw-digit-press - A digit was pressed. Detail: `{ digit: string, digits: string }`.
 * @fires sw-dial        - User pressed the call button. Detail: `{ digits: string }`.
