/* feelgood.fm colours. The station's orange #ff440f and pink #f31e58 are too light for text
   (3.4:1 and 4.1:1 on white), so they appear only in decoration (header line, equalizer, logo);
   text, buttons and badges use darker shades of them.
   Every text/background pair is at least 4.5:1 and every control border at least 3:1, in
   both themes. Colour never carries meaning alone: unread counts, "neu" and the open chat
   are also text or aria-current. */
