SG-01: The signature page is read from two grahas, not the lagna

The lucky day, colors and numbers come from two planets in the chart. These are the ruler of the rising sign and the ruler of the Moon sign. They do not come from the rising sign alone. So two people with the same rising sign can get different results.
