Epic FC Barcelona Heritage Poster

Create a dramatic vertical football tribute poster in a dark cinematic mixed-media style, combining fine-art portraiture, sports branding, textured grunge painting, and premium editorial typography. The central subject is a waist-up portrait of {argument name="historical figure" default="Rabindranath Tagore"} reimagined as an FC Barcelona icon, facing slightly to the right, with long wavy silver-gray hair, a long flowing beard, aged features, and a calm legendary presence. Dress him in a classic FC Barcelona home jersey with deep red and navy vertical stripes, visible sportswear brand swoosh on the left side, and the FCB crest on the chest. Use moody rim lighting and painterly highlights around the hair and shoulders so the figure feels monumental and almost divine. Set the background as an abstract brush-texture composition in Barcelona colors, dark indigo, crimson, burgundy, and muted gold, with 3 major graphic elements behind the portrait: a large faded FC Barcelona crest near the top center, a vertical block of handwritten Bengali manuscript text on the left side, and a large gold handwritten signature-style script running vertically on the right. At the top left, place 5 lines of elegant serif text: the first line reads "RABINDRANATH", the second much larger line reads "TAGORE", the third line reads "1861-1941", the fourth line is the quote "Where the mind is without fear and the head is held high...", and the fifth line is a cursive signature reading "Rabindranath Tagore". In the middle-lower area, add 5 centered text lines in a refined poster layout: "MORE THAN A POET.", then a large gold handwritten line reading "A timeless spirit.", then "A {argument name="club nickname" default="CULER"} FOREVER.", then a thin horizontal red-and-blue accent line, and then a small centered FCB crest beneath it. At the bottom, show a wide view of Camp Nou at dusk with glowing stadium lights and a dramatic sunset horizon, packed stands, and a giant crowd mosaic reading exactly {argument name="stadium slogan" default="MES QUE UN CLUB"}. In the foreground place 1 football centered on the wet reflective pitch with the Barcelona crest visible on the ball. The entire image should feel like a luxury fan-made heritage poster, ultra-detailed, painterly, emotional, reverential, high contrast, textured, epic, and suitable for a premium social media football graphic or wall poster. Use a tall 2:3 poster composition with layered depth, subtle sparks, paint streaks, and gold accents. Optionally replace the visible club identity with {argument name="football club" default="FC Barcelona"} while preserving the same elite tribute-poster aesthetic.
