健身教練徵才圖卡（運動雜誌風）

prompt

Create a square 1:1 Instagram recruitment graphic for {studio_name}, a boutique fitness studio hiring a {position}. Style: bold athletic editorial — dynamic diagonal composition, high-contrast charcoal background, an energetic {accent_color} gradient sweep with motion-blur light streaks, and an oversized condensed sans-serif headline 'JOIN OUR TEAM' across the upper half. Add one athletic figure in silhouette mid-movement, non-identifiable, never a posed model's face. Reserve the bottom quarter as clean dark space where the studio will overlay {perks} text later. Crisp studio lighting, minimal clutter, no real brand marks; gym equipment appears only as soft out-of-focus shapes.
