Gouache painting, Rococo, vibrant saturated colors, lantern-lit, symmetrical composition. A gilded, ornate parlor mirrored left and right, its center a single old letter unfurling from a wax-sealed envelope like a blossom. Warm lanterns hang overhead, glowing amber on rose-pink walls and cherub frescoes. An empty velvet chair waits, patient, as the letter opens. Mood: hushed revelation, nostalgic elegance, tender suspense.
