   PodFetch mdbook skin
   -------------------------------------------------------------
   Layered on top of mdbook's built-in stylesheets via the
   `additional-css` hook in book.toml. Overrides only what we
   need to match the PodFetch UI palette (mustard accent, stone
   surfaces, Geist typography). Keeping it additive means new
   mdbook releases keep working - if a base token changes we
   inherit it automatically.
