/* Colors are the launcher's palettes (src/core/config.cpp, darkPalette and lightPalette).
   index.html sets data-theme before first paint; dark is the default without JavaScript.
   The launcher's light status colors are under 4.5:1 as text, so --success, --warning,
   --soon and --link carry darker light-theme values; the P1-P4 fields keep their hues.
   One motif runs the page: the four player slots (P1 hosts, P2-P4 join). It is the field under
   the hero, the pips on every game, the player picker, the four steps and the footer blocks. */
