/* ============================================================
   BC1 — Building a Company of 1
   Stylesheet v2

   Design direction — "one stroke"
   ------------------------------------------------------------
   The whole page hangs off a single vertical hairline in the
   left margin. It begins at the top of the hero as the stem of
   a numeral 1 and ends in the footer on the foot of that same 1,
   above the mark. One person, one line, one company.

   Ground is cool Bristol chalk, not warm cream; display type is
   a heavy tight grotesque in sentence case; body copy is set in
   a serif — the inverse of the usual pairing, because what this
   programme produces is a record of work, not a pitch.
