YouTube Thumbnail - Reinecke Undine Forest Title Card

Create a cinematic horizontal title card for a classical music video about {argument name="composer and work" default="Reinecke: Undine"}. Use a 16:9 widescreen canvas. The scene is a dark Romantic forest at night, filled with blue-gray mist and water vapor, with a shallow reflective pool along the bottom edge. A powerful diagonal shaft of cold moonlight enters from the upper right and illuminates a ghostly water spirit or undine standing near the lower center, small in scale, with very long pale blonde hair and a translucent silver-blue gown that blends into the fog and water. Frame the image with exactly 9 prominent black tree trunks in the foreground: 5 clustered on the left side and 4 on the right side, with thin hanging branches and moss near the top. The atmosphere should feel mysterious, mythic, and operatic, with deep greens, blacks, cyan-blue haze, and soft volumetric lighting. Add bold title text in the upper left: exactly 2 lines, line 1 reads {argument name="top title text" default="Reinecke:"} in white, smaller bold sans-serif, and line 2 reads {argument name="main title text" default="Undine"} in large bright yellow bold sans-serif with a subtle dark shadow. Keep the typography clean and highly legible, leave the rest of the image free of text, no logos, no watermark.
