SVGs can be minified after edition, but of course nothing will beat hand-crafted SVGs…

Vector images can be a good fit though! If you can fit a URL in there, a SVG could fit in too :)

That’s also why i love the rust ecosystem. If you have rust installed and have your local dependencies (or only use the standard library), the docs can be generated locally (cargo doc). I certainly remember local manuals helping me out more than once over the years :)
