/* Multi Machine fleet theme — framework-free, drop-in.

   Light, with a pixel-art edge borrowed from the logo: square corners, hard
   two-pixel outlines, and flat offset shadows with no blur, so every edge
   lands on a whole pixel. Colours are sampled straight out of logo.png —
   the red body, the steel blades, the near-black outline. The page
   background is an isometric striped floor built from --bg, echoing the
   isometric logo.

   Sizing is deliberately unchanged from the first theme: same type scale,
   same paddings, same 720px column. Only the palette and the edges moved. */
