Copy `adminer.css` alongside Adminer PHP script to use an alternative design.
If the design supports dark mode then it should be named `adminer-dark.css`.

Each design starts with a `/* Adminer design <name> */` comment matching its directory name.
Adminer uses it together with a checksum to mark a used design not matching the current Adminer version.
