Expansive Bright Blue Sky with Wispy Clouds

expansive bright blue sky with soft gradient from deep azure at upper left to pale cyan at right, delicate wispy cirrus streaks sweeping diagonally across the upper sky, small fluffy white cumulus clouds clustered low near the horizon, minimal clean landscape with no ground visible, airy open negative space, realistic stock photography style, crisp natural daylight, subtle atmospheric haze, serene summer weather, wide-angle view, sharp but soft cloud textures, uncluttered background, no text, no watermark
