Skytrain of Luminous Light Arc

Depict a serene, otherworldly sky train made entirely of pure luminous light arcing above a silent city block, intended as a vertical 9:16 cinematic digital painting that feels calm and contemplative; the train's carriages form a continuous ribbon whose gradient shifts gradually from icy blues at the lead (#00AEEF, #7FDBFF) to warm golds (#FFD166, #A0844A) toward the rear, the glow appearing slightly translucent and glassy with soft inner bloom and gentle trailing light. Place the elevated track horizontally across the center third of a vertical frame (9:16 crop), the arc sweeping left-to-right and filling the midground so there is generous negative space above and below for atmosphere. Keep the buildings below intentionally minimal, blocky silhouettes in deep matte charcoal and near-black (#0B0F12), with few dark windows and no street activity so the train's radiance is the sole focal point. Behind the final carriage, render the numerals "2026" as unfurling floating light traces—thin, warm-gold filament strokes that dissolve into faint particles as they trail away. Populate the surrounding air with subtle drifting particles and faint bokeh specks that catch the train's spectrum, moving very slowly to imply calm; add a barely perceptible motion blur on trailing edges of carriages to suggest gliding motion. Light quality is soft and clean, cool highlights on the blue end, warm rim glow on the gold end, mild volumetric haze around the track to emphasize depth without obscuring shapes. Composition: centered elevated track across the frame, horizon low, strong horizontal line for stability, balanced negative space above for the sky and particle motion; overall mood gentle, quiet, and slightly awe-struck.
