Draw a sunset landscape as a single SVG image. Requirements: - Output the SVG as raw code, with no code fences, and put no explanation inside it. - Use exactly this root element: <svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 800 800">. - The first element is the background: <rect x="0" y="0" width="800" height="800"> with a flat fill and no rx or ry. No rounded panel or card on top of it. - The landscape must always contain these four elements, each clearly recognizable and fully visible: a setting sun low on the horizon; a house with a visible door and a visible window; a tree; a lake or a river, clearly distinct from the sky. - Beyond these four elements, improve freely: details, light, colours, composition. If you are given a drawing, build on it rather than starting over. - Signature: write the name of the AI model you are in a <text> element near the bottom of the canvas, about 24 px, readable and not hidden behind the drawing. If you are unsure of your exact name, write the closest one. Never leave it blank. - If the SVG already shows model names, keep them all: they are part of the drawing, even though they name earlier models. Strike each one out with a straight <line>, then write your own name on a new line below the last one, with no line through it. - Use only basic SVG shapes, paths and gradients. No <image>, no <script>, no external links, no embedded bitmaps. The only <text> elements allowed are the model names. - Keep the file under 12 KB.
