Create a dramatic cinematic historical collage in a wide 16:9 format about a lost classical music masterpiece. The scene is split diagonally by torn parchment and black-gold paint textures. On the left, show a terrified young mother in an 18th-century cream linen dress fleeing through a dark rain-slick European city street while clutching her small curly-haired son in her arms; behind them, a shadowy armed husband pursues them through blue fog near baroque church silhouettes and old street lanterns. On the right, show an elderly 18th-century composer, about {argument name="composer age" default="84"} years old, with white powdered hair and a black velvet coat, seated at a candlelit wooden desk writing musical notation with a quill on manuscript paper. Behind him, include two sepia portrait busts or painted composer portraits, one with a rough red brushstroke across the eyes to suggest misattribution and historical mystery. Overlay the entire image with exactly three prominent manuscript-music elements: one sweeping golden staff of notes across the upper center, one torn sheet of musical score across the lower center, and one smaller red-and-gold notation fragment in the lower left. Add scattered gold ink splashes, black soot textures, torn paper edges, a red wax seal near the lower right, stacks of old papers, brass candlesticks with lit candles, and deep chiaroscuro lighting. Use a baroque thriller aesthetic, ultra-detailed painterly photorealism, moody blue shadows on the fleeing figures, warm amber candlelight on the composer, high contrast, textured parchment background, no modern objects, no readable text, no watermark.
