Fix mobile experience: overflow, reflow, and crisp menu

- Collapse all multi-column section grids to single column on <=980px (the
  inline grids lacked responsive classes); keep the comparison matrix
  horizontally scrollable via its existing overflow-x wrapper.
- Scale down hero h1 and section h2 so long words no longer overflow the
  viewport; add a <=430px tier for small phones.
- Remove backdrop-filter blur from the nav drawer and menu button (their
  backgrounds are opaque) so the open menu renders crisp instead of blurry.
- Tidy the top meta bar: trim padding, clear space for the floating menu
  button, hide the decorative coordinates on small screens.
- Constrain images to 100% width on mobile.
