 *  Theming contract for OpenBench.
 *
 *  DARK is the original OpenBench skin, restored value for value. Every
 *  literal that used to be hard-coded in a rule below now lives in a custom
 *  property whose dark value is that exact literal, so the dark page renders
 *  as it always did. The variables exist purely so a second palette can be
 *  swapped in; they are not an invitation to re-tune the dark colours.
 *
 *  LIGHT follows fishtest (tests.stockfishchess.org), which is Bootstrap 5.3
 *  with a green link colour. Sampled from the live site:
