 * Black and white, Archivo Black for display, Roboto for reading. The warm

 * here; the two sites are now siblings in structure, not in colour.
 *
 * Ink is #111 on #fcfcfc rather than pure #000 on #fff. At 21:1 the pure
 * pairing glares on long text; this holds 18.41:1 and reads calmer without
 * softening the character of the type. Every pair below was measured
 * against the darkest grain pixel (#f5f5f5), not the flat background.
