/* Word Grid Games — wordgridgames.com
   Editorial stylesheet. Deliberately unrelated to the Word Night product site.
   No external requests: system fonts only, no images, no script.

   The motif is the letter tile — one square with a hairline rule, at four scales:
   the 2x2 board mark in the masthead (same shape as the favicon), the numbered tile
   on a ranked entry, the filled/hollow tile on a pro/con line, and the heavy rule
   that separates sections. Everything else gets less decoration, not more. */
