Marked up by hand
Use cases are now marked up in pen: the line that matters most is highlighted or underlined, some with a margin note, so you can skim for what counts.

Fixes and improvements
- A new mark: a coral stamp beside the vetted.tools name, and a favicon to match
- Tool pages carry a seal when one of our use cases runs the tool
- Client work is a wall of cards, each in the client's own colours, with a fourth case added
- The home page's picture is the real tools page, marked up in pen
- Technical level reads out of 5 everywhere, the markdown copies included
