Colors in the UI don't have enough contrast

[stof]

The light blue color used in the UI has a contrast ratio of 2.58 with the white background (see https://contrast-ratio.com/#%231EAEDB-on-white), which is far below the AA level of WCAG (which is at 4.5).

While this is mostly fine on the homepage (the only links are the names of implementation), I find that it makes the FAQ quite hard to read (the table of content being full of links for instance).

There is another contrast issue for the heading of results. Its gray color has a contrast ratio of 1.6 for the text (https://contrast-ratio.com/#%23ccc-on-white) while AA criteria for large text is 3. And the heading-info with the number of implementation has a ratio of 3.54 (https://contrast-ratio.com/#%23888-on-white) while it does not qualify as large text.
