Illustration balnéaire : phare au coucher du soleil

Flat illustration of a red-and-white striped lighthouse standing on a rocky cliff by the sea at sunset, the lighthouse with a glowing amber lantern room, a small curved iron balcony and a weather vane on top, seagulls circling the tower, a winding stone path with two tiny hikers carrying a green flag, waves curling with white foam crests against the rocks in stylized repeating curves, a lone sailboat with a rust-orange sail floating on the calm water, layered flat shapes with clean crisp edges, no outlines, limited soft shadows and subtle paper grain, composition using the lighthouse as a strong vertical focal point on the right third with the horizon line placed on the lower third, warm golden sunlight from the left horizon casting long lavender-purple shadows across the cliff, palette of coral, peach, navy blue and cream, bright cheerful minimal poster style, clean geometric simplicity, high resolution, 4k
