   Building view: the pixel office. Every rect is absolutely positioned on
   .building-layer in cell units (--x --y --w --h against --cell). Walls are
   thick borders, floors are two-tone tiles tinted by the group colour,
   bands get carpet, doors sit on walls, corridors are one SVG overlay.
   The pixel font loads lazily (avatar.js) and falls back to monospace.
