   15. Narrow-screen overflow fixes
   ------------------------------------------------------------
   Several pages scrolled sideways on phones. Two root causes:

   a) `.btn` sets `white-space: nowrap`, so a long CTA such as
      "Identify Your SEO Issues — Free Audit" had a min-content
      width of ~440px. Inside a grid it forced the whole column
      (and the page) wider than the viewport.

   b) Grid and flex children default to `min-width: auto`, which
      refuses to shrink below their content's minimum width, so
      that 440px propagated all the way up to <body>.
