/* ============================================
   Text selection
   ============================================
   Without a rule here the browser paints its own selection colour, which no
   palette can reach: the dark layer had a themed one (dark-mode/editor.css)
   while every light theme showed a grey or a blue nobody had chosen, and in
   the same note the markdown editor, which draws its own, showed the accent.
   That is the second half of #1424.

   --pz-selection is the one value: the markdown editor, which draws its own
   selection instead of letting the browser paint it, reads the same token, so
   a selection looks the same in read and in edit mode. The token switches with
   the theme, so this rule is written once and needs no dark counterpart. */

    background-color: var(--pz-selection);
