There is some rather low-hanging fruit to improve accessibility (`alt` on images, `aria-label` on text fields or dropdowns, `title` on links) according to [Lighthouse](https://en.wikipedia.org/wiki/Lighthouse_(software)) ([docs](https://developer.chrome.com/docs/lighthouse/)) which is integrated in Chromium and useful to identify some trivial ones.
I plan to provide a bunch of patches.
