A heavily modified Bento theme
Slight modification to colour for valid contrast

#e54028 had less than 4.5:1 luminosity contrast ratio.
#e52a08 has just over 4.5:1, which meets WCAG 2.0.

Ensuring the source checkboxes look decent on mobiles
fixing header markup and some style tweaks

The two links are really buttons that perform actions. So don’t need
<nav>. Renamed relevant class names. Added clearer hover/focus styles
to buttons. Removed @aria-selected.

fixing header markup and some style tweaks
some semantic markup changes to the Customise dialog

made dialog container a section; added ARIA attrs; used <header> and
<footer> for dialog header and footer; moved intro paragraph into
<header> so is always visible; replaced sections and h3s with fieldsets
and legends; made buttons into <buttons>; tweaked CSS accordingly; note
that some stylings not exactly as before…feel free to tweak further as
desired.
