Create a finished vertical typographic art poster, 3:4 ratio. Render only these four text strings, exactly: “Open the Gate” as the large English headline; “فتاح الباب” as the smaller Arabic line, set right-to-left with correctly connected Arabic calligraphy; “THRESHOLD STUDY” as a small uppercase eyebrow; “OPTICAL GLASS · 01” as a small footer. No other lettering, logos, or watermarks. Make the two headline lines the unmistakable centerpiece. Draw both in custom elegant cursive lettering with elongated sweeping joins, narrow oval counters, varied stroke weight, fine tapered terminals, and clear separation between letterforms. Preserve readable English letter shapes and correctly connected Arabic forms. Sculpt every glyph from pure, high-clarity, untinted optical crystal glass: deep internal optical depth, transparent bodies revealing and slightly distorting the background, precise parallel facets along thick edges, thin bright edge highlights, focused glass caustics, and restrained rainbow dispersion at extreme angles. Give curves and terminals a subtle liquid-pulled surface tension. Keep the letter surfaces clear, not milky or opaque. Stage a tall, open arched gate made from two slim clear-glass uprights and a curved glass lintel behind the lettering; leave its center open and use it as a secondary sculptural subject, not a barrier across the words. Put the headline across the central upper-middle area and the Arabic line directly below it. Place the eyebrow near the top margin and the footer near the bottom. Use a softly graded lavender-blue background, a pale reflective plane under the gate, and soft caustic light patterns beneath the glass forms. Diffused lavender-blue backlight passes through the arch; narrow white speculars trace crystal edges. Clean high-end product-render lighting, physically accurate refraction, subtle depth of field, crisp readable lettering, ample negative space, balanced poster margins. Avoid dark dramatic staging, opaque glass, heavy bloom, clutter, and extra copy.
