Server picks variant from Lisbon-local date (rain/petals/jacaranda/motes/leaves) and renders behind content via a canvas particle layer. Each variant has a hand-drawn silhouette so shapes are recognizable. /weather demo route exposes variant + intensity + phase pickers, locking the time-of-day phase override.
