/* Bindu — light and dark themes, element-coded signs, printable chart.
 *
 * Two rules from the plan are structural, not decorative:
 *  - meaning is never carried by colour alone: every tinted cell also has its
 *    sign written out, and retrograde or warning states carry a mark or a word;
 *  - colours are declared in pairs and checked for contrast in both themes.
