+Use case: stylized-concept
+Asset type: background artwork for the RustRaptor game main menu, no text or UI baked into the image.
+Primary request: modern HD reinterpretation of a classic 1990s top-down military sci-fi shoot-em-up menu atmosphere, cohesive with silver gunmetal spacecraft and dark red accents.
+Scene/backdrop: a quiet futuristic coastal aircraft hangar at dusk, looking toward a blue-grey ocean and distant storm-lit industrial shoreline. One compact silver gunmetal fighter with dark red trim is parked near the lower left foreground, viewed from above and slightly behind. Restrained amber hangar lights, subtle steel paneling, atmospheric depth.
+Composition/framing: wide landscape 16:10 composition. Keep the upper quarter and the entire right half low contrast, dark navy and visually quiet for overlaid menu controls. The spacecraft and most scenery detail occupy lower left and edges. Give the art a cinematic hand-painted game illustration finish with crisp mechanical detailing, not photographic clutter.
+Color palette: deep navy, cool slate blue, silver gunmetal, restrained dark red and warm amber accents, readable dark negative space.
+Constraints: no people, no lettering, no logos, no buttons, no watermarks, no interface panels, no combat explosions. This is a game background asset; the actual menu text is rendered separately. High resolution.
