+
+## business_shark
+
+Use case: stylized-concept. Final production square ability icon for a realistic painterly space RPG. Highly polished hand-painted digital game art, cinematic material detail, strong simple silhouette readable at 40 pixels, centered composition with 12% safe margin. Dark navy outer corners, restrained luminous accent, no text, no letters, no numbers, no interface, no border. One iconic subject, not a scene. Business Shark passive skill: an elegant gold metallic shark emblem curling around a small stack of futuristic credit coins, warm amber highlights, brushed gold and deep charcoal materials, confident mercantile space captain mood.
+
+## reactor_overload
+
+Use case: stylized-concept. Final production square ability icon for a realistic painterly space RPG. Highly polished hand-painted digital game art, cinematic material detail, strong simple silhouette readable at 40 pixels, centered composition with 12% safe margin. Dark navy outer corners, restrained luminous accent, no text, no letters, no numbers, no interface, no border. One iconic subject, not a scene. Reactor Overload active skill: a compact circular spaceship fusion reactor with a brilliant cyan-white energy core inside heavy gunmetal containment rings, vivid electric blue arcs escaping the core, teal glow illuminating machined metal, dynamic energy, clear large central reactor silhouette.
+
+## tactical_maneuver
+
+Use case: stylized-concept. Final production square ability icon for a realistic painterly space RPG. Highly polished hand-painted digital game art, cinematic material detail, strong simple silhouette readable at 40 pixels, centered composition with 12% safe margin. Dark navy outer corners, restrained luminous accent, no text, no letters, no numbers, no interface, no border. One iconic subject, not a scene. Tactical Maneuver active skill: a sleek silver spacecraft banking sharply diagonally upward, two curved violet-blue contrails sweeping behind it to show an evasive turn, a faint ghost silhouette of its former position, purple light on metallic hull. Strong clear ship shape and dramatic diagonal movement.
+
+## efficient_magazine
+
+Use case: stylized-concept. Final production square ability icon for a realistic painterly space RPG. Highly polished hand-painted digital game art, cinematic material detail, strong simple silhouette readable at 40 pixels, centered composition with 12% safe margin. Dark navy outer corners, restrained luminous accent, no text, no letters, no numbers, no interface, no border. One iconic subject, not a scene. Efficient Magazine passive skill: a robust gunmetal ammunition magazine with three large brass-tipped futuristic kinetic cartridges, a luminous green circular recycling arrow wrapping around the cartridge group, sage-green accent light, realistic brushed metal, unmistakable ammo conservation emblem.
+
+## miner
+
+Use case: stylized-concept. Final production square ability icon for a realistic painterly space RPG. Highly polished hand-painted digital game art, cinematic material detail, strong simple silhouette readable at 40 pixels, centered composition with 12% safe margin. Dark navy outer corners, restrained luminous accent, no text, no letters, no numbers, no interface, no border. One iconic subject, not a scene. Miner passive skill: a rugged futuristic plasma mining pick striking a small jagged asteroid rich with large bright titanium and copper mineral veins, a few amber sparks at impact, dark metal tool with worn industrial edges, warm copper and steel-blue material contrast, clear bold pickaxe-and-rock silhouette.
+
+## power_redirect
+
+Use case: stylized-concept. Final production square ability icon for a realistic painterly space RPG. Highly polished hand-painted digital game art, cinematic material detail, strong simple silhouette readable at 40 pixels, centered composition with 12% safe margin. Dark navy outer corners, restrained luminous accent, no text, no letters, no numbers, no interface, no border. One iconic subject, not a scene. Power Redirect active skill: a heavy metallic spaceship shield emitter on the left splitting open and releasing a powerful curved orange-gold energy stream into a bright compact cyan reactor core on the right. A bold luminous flow of power visually connects the two components. Burnt orange, pale gold, electric teal highlights, realistic sci-fi machinery, strong simple two-part silhouette.
