节日临时厕所：模块化与快速拆装

Design a temporary toilet installation for a festival, treated as a piece of designed infrastructure rather than a row of plastic boxes. Show a linear arrangement of modular units on a raised timber deck platform with ramped access at both ends, so the whole facility is level and accessible on rough ground. Detail the units as identical prefabricated cabins clad in a single strong colour with clear numbering, arranged back-to-back in two rows sharing a central service spine that carries the tanks and pipework, screened behind a louvred panel. Show a proper wash station as a separate element — a long trough with many taps under a fabric canopy — positioned so its queue does not tangle with the cubicle queue. Detail the wayfinding as tall flags and illuminated numbers visible across a crowded field at night. Show a lit route to the facility marked by ground-level lights. Include a queue managed by simple barriers, and a service vehicle at the rear. Show evening with the site lit. Photorealistic, organised, saturated colour against dusk, three-quarter view.
