Anime Boxing Title Match Poster

A dramatic Japanese boxing match poster in a polished anime illustration style, vertical composition, split straight down the center into warm gold on the left and electric blue on the right. At the very top, huge metallic gold embossed lettering reads {argument name="headline text" default="JUNGLE PREMIUM Vol.7"}, with a bright glow and beveled 3D effect. Directly beneath it, centered white Japanese text reads "世界4団体フェザー級タイトルマッチ". Show 2 male featherweight boxers facing each other in fighting stance inside a boxing ring, both full body, highly muscular, lean, and sharply defined with glossy skin highlights. The left boxer is a blond anime-style young man with short tousled hair, wearing gold boxing gloves, black-and-gold trunks with a white-red accent on one leg, black boxing boots with gold laces, and a thick championship-style waistband patch reading "SEIJI". He stands on the gold side with explosive golden sparks and streaks surrounding him. The right boxer is a black-haired anime-style young man with short spiky hair, wearing bright blue boxing gloves, dark navy-blue trunks, blue boxing boots, white socks, and a waistband patch reading "JUNICHI". He stands on the blue side with swirling blue energy, light trails, and glowing particles. Place a circular championship belt emblem in the center background between them, with ring ropes visible behind, and the words "WORLD CHAMPION" legible on the belt medallion. Add 2 large faded portrait overlays in the background, one behind each boxer: the left background portrait tinted gold and the right background portrait tinted blue. Along the far left side, place bold vertical Japanese calligraphy reading "黄金の閃光" in glowing white-gold. Along the far right side, place bold vertical Japanese calligraphy reading "蒼き鉄拳" in glowing white-blue. At the bottom, feature 2 very large Japanese name blocks: left in gold reading "松浦聖司", right in icy blue-white reading "藤原潤一", with a blazing gold "VS" between them. Beneath that, centered large white date text reads {argument name="event date" default="7月19日(日)"}. At the very bottom, centered gold serif text reads {argument name="venue name" default="SUN BIRTH STADIUM"}. Use extreme contrast, cinematic arena lighting, energetic particle effects, premium sports-event poster design, glossy typography, and a heroic high-stakes championship atmosphere.
