/* Word Count for PowerPoint: the website (help.html, index.html).
   The task pane has its own stylesheet (taskpane.css).

   Direction: warm and editorial, built around counting. Sections are numbered with
   tally marks (I, II, III, IIII, then a crossed five for the last one). The icon's
   bright orange-to-pink gradient is used for glow and decoration only; text and
   buttons use deeper shades of the same colours so they stay readable (checked for
   WCAG AA contrast in light and dark mode). */
