Fictional Triple Crown Horse Poster

A dramatic Japanese horse racing champion poster in a cinematic, high-contrast, premium sports-advertising style. The main subject is a powerful dark bay to nearly black Thoroughbred racehorse with a glossy coat, a slightly windswept mane, and a small white star on its forehead, shown in a dominant three-quarter full-body pose facing right-of-camera. The horse wears racing tack and a deep blue saddlecloth marked with a large white number 7 and the horse name in Japanese, horse_name. Use a dark navy, black, and metallic gold color palette with glowing highlights, mist, sparks, and a night-sky atmosphere to create a legendary, triumphant mood. The layout should feel like an elite championship poster: oversized gold Japanese headline text at the upper left reading main_headline, with a smaller gold subtitle beneath it reading 「その名は、頂点の制御者。」. On the left side, include 3 laurel-wreath achievement callouts stacked vertically, each in gold: 1) 「皐月賞」 with smaller text 「中山競馬場 芝2000m」, 2) 「日本ダービー」 with smaller text 「東京競馬場 芝2400m」, 3) 「菊花賞」 with smaller text 「京都競馬場 芝3000m」. Across the bottom left to center, place the horse’s name in huge textured metallic gold Japanese lettering, horse_name_large, with the romanized name CONTROL in spaced serif capitals below it. Beneath that, add a pedigree line in gold Japanese text: 「牡・青鹿毛　父：sire_name」. On the right side, add a large semi-transparent portrait of an older male trainer in a cap and glasses emerging from the dark background, serious and authoritative, with vertical white slogan text along the far right edge reading 「心を制し、レースを支配する。」. Near the trainer portrait, include handwritten-style white calligraphy for the trainer credit: 「調教師」 followed by a large signature-like name trainer_name, and a smaller white phrase beneath: 「信念は、勝利を支配する。」. At the bottom right, show 3 smaller action panels or cutout scenes of the same horse racing with jockey, each tinted in cool blue tones and labeled in gold beneath them: 「皐月賞」, 「日本ダービー」, 「菊花賞」. The composition should be dense but elegant, with layered smoke, stadium lights, gold dust, and sharp contrast, resembling a luxury commemorative poster for a fictional Triple Crown racehorse.
