/* iainMail
   Reading-first mail. One column, one thing at a time.

   The rules behind the look:
   - Never pure white on pure black. Bright text on true black smears at the
     edges (halation), which is tiring for everyone and worse for some. Warm
     off-white on a warm near-black instead.
   - Line length is capped. Long lines lose your place on the return sweep.
   - Space is structure. Gaps do the work that borders and boxes usually do.
   - Emphasis is weight and colour, never italics.
