Generate a tactile tabletop miniature city during a rain test. Preserve the six-block layout, pale wood buildings, blue ceramic channels, and central glass reservoir from Image 1. Follow the water path in Image 2 exactly: roofs → gutters → street channels → filter garden → reservoir.

Opening macro: controlled rain begins over one block; droplets collect on sloped roofs and enter tiny gutters. Camera follows one stream at miniature height as it joins the street channel and moves downhill. Middle overhead: water passes through the planted filter garden; the flow becomes visibly clearer without an instant magical change. Final wide: the central reservoir level rises slightly while a small mechanical indicator moves from low to medium.

Use real surface tension, scale-appropriate droplets, wood darkening, and ceramic reflections. Sound intent: close rain, small water trickle, mechanical click. Avoid real skyscraper scale, floods, invented labels or efficiency claims, reverse water flow, extra buildings, people, logos, or watermark.
