/* ==========================================================================
   JoJoeKing — King of Curses
   Palette: void #050505 / #0a0a0b · blood #c1121f → ember #ff1f2d · bone #e9e4da

   Type: Shippori Mincho B1 700 is the one display face: the name, the
   呪いの王 accent and the 領域展開 overlay. A Japanese mincho whose Latin was
   drawn to sit beside kanji: brush-born wedge serifs, sharp hairlines and
   steady, heavy stems, so the name and the kanji read as one hand. It is
   wide (≈5.15em for "JoJoeKing"), so it is set smaller than a Didone would
   be and tracked slightly in. Subset to exactly the glyphs used (see the
   &text= list in index.html). Inter for the small tracked labels.
