Generate an SVG as a Father's Day greeting card illustration. Warm autumnal nature style. Draw a mountain silhouette at lower canvas — 3 overlapping peak shapes in deep teal (#0F766E) and slate (#334155). Above the mountains, a starry night sky: scatter 12 small 4-pointed star dots in amber (#FBBF24) and cream (#FEF3C7). Add a large campfire shape at lower-right — log shapes in brown (#78350F), flame in orange (#F97316) and amber (#FBBF24). Warm dark sky background in #0F1825. No text, no labels, no emoji. Output raw SVG code only starting with <svg.

The image shows a poster with the words "Father's Day" written on it, surrounded by a campfire with wooden sticks and mountains in the background.
