Galaxy Rail Title Screen

Goal: Create a retro 2D vertical arcade game title screen for a rail shooter called GALAXY RAIL, with a space-and-railroad theme and Japanese UI text. Canvas: Portrait mobile game splash screen, 9:16 aspect ratio, pixel-art inspired but clean vector-like illustration, dark navy outer-space background filled with many small white and pale yellow stars. Layout: Center the title in the upper-middle. Place a large partially cropped Earth-like blue planet on the left behind the title, occupying about one third of the image height, with simple green landmasses and translucent cloud streaks. Add exactly 3 vertical railroad tracks running from top to bottom: one left track partly over the planet, one center track, and one right track; each track has gray rails and many brown sleepers. Put exactly 2 small train/player cars on the lower center track, stacked vertically with rounded white bodies, blue windows, yellow outlines, and a yellow headlight on the top car. Text content: Main title text is two lines: “GALAXY” in large white slab-serif letters with a dark navy outline, and “RAIL” below in large golden yellow slab-serif letters with a dark navy outline. Under the title, show the Japanese tagline 銀河を、レールで切り拓く in bright cyan. Beneath it, add small gray feature text: “RAIL SHOOTER / 2D VERTICAL / 3 STAGES”. In the lower third, add a translucent dark blue rectangular instruction panel with a thin blue border. Inside the panel, show three Japanese instruction lines: “←→↑↓ / WASD：移動（レールから自動ジャンプ）”, “Z / SPACE：短押し＝単発 / 長押し＝2連射”, and “時間経過で最寄りのレールへ強制着地”. Below the panel, add a small red warning line: “赤いサークル＝瞬着攻撃の予兆。収束前に発生源を倒せ！” At the very bottom, centered, show pale gray prompt text: PRESS Z SPACE OR CLICK TO START. Visual style: Retro arcade title screen, simple 2D game mockup, crisp shapes, slightly pixelated typography, high contrast, deep-space palette of navy, white, cyan, yellow, gray, and red. The composition should feel like a vertical rail shooter prototype splash screen. Constraints: Use exactly 3 full-height vertical tracks, exactly 2 train cars, one planet on the left, one instruction panel, and no characters or extra UI windows. Keep all text legible and centered, with no logos or watermarks. Insert discreet watermark in the lower right corner of the image, vertical text (rotated 90°), written "aipromptlabs.online", Calibri Light font, white color with low opacity (semi-transparent), medium size. Extreme sharpness on the face, fabric texture and typography of the letters. Shot on Canon EOS R5, 50mm f/2.8, studio light.
