/* Justice Engineering: one stylesheet for justice.engineering and shop.justice.engineering.
   The rules it follows are written up in GRID.md. In short:
   - Format: 1248px type area; margins 16 / 32 / 48; 12 columns; gutters 16 / 24.
   - Rhythm: 8px unit. Line heights on a 4px half-line; every margin, padding and gap on the 8px unit.
   - Type: classical scale, 11 12 14 16 21 24 36 48 72. Two weights, 400 and 500. Sizes step at
     breakpoints; nothing is fluid.
   - Composition: everything hangs from column 1; labels sit above what they name, not beside it.
   - Rules: hairline (1px grey) between rows, 1px black over a section, 4px black under a masthead.
   - Colour: black on white. Photographs and renders keep their own colour. */
