/* Slate & Rust-ember theme for the Spark Connect Rust Client docs.
   A near-black slate chrome with a warm rust-ember accent - a nod to Rust's
   identity, kept understated. Tuned for both the light (default) and the slate
   (dark) schemes. Colors live here as CSS custom properties; mkdocs.yml sets
   `primary: custom` / `accent: custom` so Material picks these up. */
