Create a rangoli design for Diwali that my family can recreate by hand at our front door in about {{time_available}}, with helpers who are {{age_range}}. Show it as a flat, top-down view on a smooth stone floor: a design with eightfold radial symmetry, a lotus at the center, rings of petals and dots, and small diya shapes at the four outer points. Use clean white outlines, as if drawn with rice flour, and fill the shapes with colored powder in marigold, crimson, turquoise, leaf green and violet, with a few real flower petals at the rim. Keep lines bold and shapes big enough to fill by hand, with detail matched to the time and helpers above. Below the image, list each color with a rough amount of powder, then the drawing order in numbered steps, starting from a center dot and guide lines. No text, logos or watermarks in the image, and nothing but the floor around the pattern. Format: 1:1 square.
