/* The Nonogram board, shared by games/nonogram.html and the profile preview.
   The look comes from CSS variables set by js/shared/nonogram-look.js:
   --nn-bg, --nn-line, --nn-ink, --nn-fill, --nn-mark, and .n3d (3D squares). --n is the size.
   A grid: the corner, the column clues, then per row its clue and its squares; a thicker line every 5. */
