/* Futoshiki (futoshiki-app.js): square cells with half a cell of space
   between them, placed by percentage in a square box (height set by JS).
   The "less than" signs sit in that space as filled SVG triangles, tip
   towards the smaller number - drawn, not typed, so they never depend
   on the device font. Given numbers are bold; a selected cell has a
   heavy frame, a hinted one a double frame, a conflict is shown
   inverted - shape and weight only, never grey. */
