/**
* Deep-clone plain objects so per-template config mutations stay isolated.
*
* Arrays, functions, and class instances (Date, RegExp, Vite plugins, …) pass
* through by reference — only nested plain-object props are copied, which is
* what `beforeRender` mutations (`config.url.base`, `config.css.inline`, …)
* touch. Sharing arrays by reference matches the parallel worker's merge.
