/* ============================================================
   How To Use — frontend section CSS (v1.5.15+).
   Replaces the inline wp_add_inline_style payload that lived
   in includes/frontend/how-to-use.php since v1.4.0.

   Markup is shape-agnostic: a single .htu-section gets layout /
   number-style / aspect modifier classes from PHP, e.g.

     <section class="htu-section
                     htu-layout-image-left
                     htu-numstyle-circle
                     htu-aspect-3-4">

   All variants share the same base structure; only modifier
   classes differ. Mobile always stacks (image on top, content
   below) regardless of layout choice — desktop-only flexibility.
