/* --------------------------------------------------------- logo wall ------
   The homepage placements wall: every mark knocked out to a flat white
   silhouette on the navy, so 37 logos of wildly different colour, weight and
   proportion read as one field instead of 37 competing brand palettes.

   filter: brightness(0) invert(1) is what does the knockout — brightness(0)
   crushes every colour to black, invert(1) flips that to white — and it keeps
   the alpha channel, so what shows is the logo's silhouette. That only works
   on art with a transparent ground: any logo still carrying an opaque plate
   turns into a solid white brick. The ten that shipped that way (the JPEG app
   icons, the Amex blue box, the white-backed PNGs) were re-cut to alpha in
   assets/images/companies rather than special-cased here.

   Six columns, not eight, so the wall runs long rather than wide, and with the
   white plates gone each logo now spans the full cell — roughly 40% larger
   than the plated version at the same container width.
