/* நவகிரக மண்டலம் — a night sky with temple gold.
 *
 * Two authentic forms carry the design rather than decoration:
 *   the navagraha shrine layout, Surya centred with the eight around him in
 *   their traditional directions, and the South Indian ராசி கட்டம், a 4x4
 *   grid whose twelve outer cells are fixed rasis with a hollow centre.
 * Graha colours are the traditional ones, not a palette invented for looks.
