/* =============================================================================
   Wijkkrant Delen — share buttons in the read-aloud bar
   -----------------------------------------------------------------------------
   This stylesheet does two things:

   1. The share buttons themselves.
   2. A handful of corrections to the existing read-aloud bar, so that the bar
      becomes one row: read aloud on the left, share on the right, status below.
      The corrections live here on purpose, not in voorlezen.css, so a new
      read-aloud version overwrites nothing of this plugin and vice versa.

   Contrast: ink (#1B1B18) on white = 16.5:1, white on green #3B7320 = 5.7:1.
   Hit area of every button: 32 × 32 px (WCAG 2.5.8 AA requires ≥ 24 × 24 px).
