   Homepage — Our Boards section (partials/_boards_home.php)
   Design: Figma "DIYKIT — Our Boards", page 03. A dark "hardware lab" band
   in both site themes on purpose: it is the one section of the homepage
   that is DIYKIT's own product line, and it should read as different from
   the catalogue grids around it. Scoped under .dkhb.
