Select accessibility settings below as required, in any order. Each new setting immediately comes into effect
on this page only, in the first instance. Once the appearance of the page is satisfactory, clicking on the
'Apply' button applies the settings to the entire website. Leaving the page without clicking on 'Apply' results
in the changes being lost. Note that page appearance may vary slightly according to the browser used.
The colour options here are not compatible with the dark-mode toggle in the header bar. If a custom dark scheme
is desired, the appropriate colours can be selected in light-mode.
