## Overview

Wclock is a simple Android always-on standby clock intended for an e-ink display. The main flow starts when Android launches the activity: it keeps the screen on, hides system bars, and presents a Compose clock with Chinese year, date, weekday, and time. The composable refreshes its calendar state once per minute and formats the displayed values. The README identifies no additional product capabilities; sampled code shows no persistence or external service integrations.
