/* Add-to-home-screen guide. Fleet-wide, framework-free companion to
   install-guide.js.

   Self-contained on purpose: the estate mixes hex tokens, HSL-triplet tokens
   and Tailwind 4 themes, so anything reading a repo's own --accent renders
   wrong somewhere. One override exists, --ig-accent, set either in CSS or via
   the script's data-accent attribute. Everything else is neutral.

   Reduced motion hides the phone demo and keeps the numbered steps: the
   animation is a nicety, the instructions are the content. */
