/* UChicago Chess Club
   ------------------------------------------------------------------
   Minimal. One sans, set tight. One colour — the club's maroon — used
   sparingly, and kept off anything that does not need it.

   Sections alternate between two whites that are barely a shade apart,
   so the page reads as one surface with quiet divisions in it. The
   footer is the only block of colour.

   The gothic is a touch, not a theme: a lancet arch used as a mask, so
   the small tiles — icon squares, officer avatars, the footer mark —
   are arched niches instead of rounded squares, and an arcade behind
   the footer at the edge of visible. Nothing else. Dates are plain.
