Square social-media typographic poster in Spanish, with a deep ink-black background fading to midnight violet at the edges. Centered headline, exact text: “ONCE UPON OUR CHILDHOOD ”, taking 70% of the canvas width. Custom uppercase geometric display lettering: very wide, heavy flat-faced strokes, rounded outside corners, compact spacing; every letter built as chrome-silver metal densely paved with tiny round clear rhinestones in precise rows. Individual faceted stones catch hard white point lights; visible prismatic micro-reflections, star-shaped lens flares at selected stone edges, and a thin electric-pink/cyan diffraction fringe along the outer letter contours. Add a slim hot-pink mirrored foil extrusion behind the letters for 3D depth, with a crisp cyan rim on the lower-right edges. A narrow specular highlight runs horizontally through each major stroke. Above, small spaced uppercase text, exact: “HECHA PARA REFLEJAR LA LUZ”. Below the headline, exact text: “cada destello cuenta”, in clean small silver sans lettering. Composition has generous black negative space, centered and symmetrical, sparse scattered crystal points and four-point starbursts only around the headline; no people, no objects, no extra words, no logos. High-detail product-photography lighting: frontal white key light, magenta light from upper left, cyan light from lower right, sharp ray-traced reflections, crisp rhinestone facets, 8k.
