/* TCMA look for the Fable manual.
 *
 * The palette, type and shape come from the TheyCallMeAlfred UI kit (TcmaTokensGame.uss in
 * the Unity project): bone paper, ink lines, square corners, hard offset shadows, lime on
 * hover. The chunky style is for the page chrome (header, cards, buttons, headings);
 * reference tables stay light so long pages stay readable.
