   The supplied logo PNG has dark lettering on transparency, so it disappears
   on a dark surface. Rather than filter the artwork (which would wreck the
   red/blue/amber diamond), the angled brand plate stays light in dark mode.
   It reads as a deliberate light card holding the mark. If a white-text
   version of the logo is supplied, delete this block and swap the src. */
