   - **Digital Clock:** Toggleable date, seconds, and blinking colon. Automatically restricts font selection to monospaced typefaces when active to eliminate horizontal layout jitter.

+- **Transient Alerts & State Restoration:** Passing a `duration` > 0 temporarily interrupts the continuous ambient display to show an alert, automatically reverting to the previous state once the timer expires.

   - Independent foreground (text/clock) and background canvas effect engines.
   - Supported effects: `solid`, `rainbow`, `gradient-h` (horizontal), `gradient-v` (vertical), and `pulse`.
