/* ==========================================================================
   /help/: how to use the app, step by step, with pictures.

   Page-scoped: every selector starts hp-, so nothing here can reach another
   page. Colours come from the site's tokens (css/styles.css) except the
   guide ring, which is the demo's blue on purpose: every button in the
   product is gold, and a gold ring around a gold button reads as the button.

   The reader is 55+, often on a phone, holding a box of prints. So: one
   thing at a time, 18px body text, captions a notch bigger, and nothing to
   press that is under 44px tall.
