   Official Google Partner badge. Rules this CSS deliberately respects:

   - clear space of at least half the badge height on every side (--gpb-gap)
   - the badge must stay visually subordinate to the Sailward wordmark, so the
     art is capped below the hero/section-heading scale and never replaces a
     heading. It still has to be legible: trust marks below ~100px read as
     decoration and get missed, which defeats the point of having one.
   - artwork is never recoloured, cropped, rotated or wrapped in a filter */
