   Shortnshare landing page.
   sns.css loads first and owns every colour, font size, radius, shadow,
   spacing value and duration via tokens. Type roles come from the sns-type-*
   classes in sns.css. This file adds only the layout that is unique to this
   page. No colour literals, no raw px for spacing, no IDs as selectors.
