/* Gabryel Lopes, email design portfolio
   Same identity as the main portfolio: navy ground, electric blue accent,
   Bricolage Grotesque + Geist. Each campaign keeps its own brand colour (--c).
   One variable for the side gutter (--gutter), one for vertical rhythm (--section).
   Every font-size is an even pixel value. Hover lives only inside @media (hover: hover). */
