Faure Requiem Poster

Goal: Create a refined square social-media editorial poster about {argument name="musical work" default="Requiem in D minor, Op. 48"} by {argument name="composer" default="Gabriel Fauré"}, presenting a calm, luminous interpretation of a requiem rather than a dark one. Canvas: 1:1 square format, 768 x 768 px. Divide the composition vertically into 2 panels: a dark navy text panel on the left occupying about 59% of the width, and an atmospheric abstract painting panel on the right occupying about 41%. Layout: Left panel uses generous margins and elegant editorial spacing. Top-left has 1 small gold square bullet followed by a small uppercase section label. The main headline sits in the upper-middle, large and dominant, broken into 4 stacked lines. Below it is 1 short horizontal gold divider line. Under the divider is a 2-line subtitle. Near the lower-left is a small gold work/composer credit in 2 lines. At the very bottom-left is a tiny footer label. Bottom-right of the whole poster has a tiny page number. Text content: Include exactly 7 text elements: 1) top label: “UNA ESCUCHA INESPERADA”; 2) main headline in Spanish, all caps with inverted question mark: “¿UNA MISA / DE DIFUNTOS / QUE SUENA / A LUZ?”; 3) subtitle: “40 minutos para descubrir / una feliz liberación.”; 4) credit line: “Réquiem en re menor, Op. 48”; 5) composer line: “Gabriel Fauré”; 6) footer: “FAURÉ · RÉQUIEM OP. 48”; 7) page number: “01”. Allow the headline to be customized as {argument name="headline text" default="¿UNA MISA DE DIFUNTOS QUE SUENA A LUZ?"} and the subtitle as {argument name="subtitle text" default="40 minutos para descubrir una feliz liberación."} while preserving the same line-break rhythm. Typography: Main headline in a bold high-contrast classical serif, white, all caps, with dramatic thick-thin strokes. Supporting text in a clean modern sans serif, mostly white; the work/composer credit is muted gold. Use strong typographic hierarchy and precise alignment. Visual style: Minimal, museum-quality, literary and sacred-music themed. Left background is deep midnight navy, almost black. Accent color is warm antique gold. Right panel is a soft abstract luminous landscape or chapel-like passage: creamy beige, pale gold, mist, subtle brush texture, a glowing curved path of light near the bottom leading into a bright hazy vertical space. No figures, no instruments, no literal church interior; keep it ethereal and serene. Constraints: Keep exactly the 2-panel composition and exactly the 7 text elements listed. No extra logos, watermarks, icons, or decorative ornaments beyond the single gold square bullet and one gold divider line. Ensure the Spanish headline is crisp and legible.
