     * IMPORTANT: This method implements the WORKING keyboard control logic.
     *
     * ⚠️  DO NOT MODIFY THIS LOGIC! ⚠️
     *
     * This simple approach works perfectly:
     * - If key is pressed → apply movement every update cycle
     * - stepSize: 8 units per cycle at 60Hz = smooth, responsive control
     * - Single taps work naturally (brief key press = few cycles = small movement)
     * - Held keys work naturally (continuous press = continuous movement)
     *
     * Previous "improvements" that BROKE this:
     * ❌ Trying to detect "first press" vs "held" - breaks everything
     * ❌ Adding delays/thresholds - makes it clunky
     * ❌ Event-driven immediate movement - causes multiple applications
     * ❌ Higher stepSize values - too large jumps
     *
     * Keep it simple - this works!
