Du toit à l'oasis urbaine - Accéléré temporel

Locked-off camera from a neighboring building looking onto a flat urban rooftop. Foreground: gravel and small planters filling ~60% of frame; midground: workers arrive with soil bags, wheelbarrows; background: distant skyline under soft, overcast sky. Time accelerates: plants sprout and sway in gentle wind; raised beds constructed; irrigation hoses laid; flowers, shrubs, and small trees planted; wooden pergola erected; benches placed; final garden decorations added. Lighting phases from bright morning to soft sunset; by dusk, rooftop lights glow warmly, reflecting on surrounding buildings. Maintain realistic scale, natural urban palette, gentle haze, zero camera motion.
