 Note: by absolute default (via inline CSS) feather icons are hidden.
 That's because firefox reader mode doesn't play nice with them, and
 it seems to ignore all styles in <head>. Then, the inline style
 in <head> uses !important to restore the display of icons, but provides
 limited styling. Here, we finally apply the full extent of the feather
 styles.
