Updated project description

Updated to: "50 mm x 50 mm power-conversion board with a 3 V input and two separate regulated outputs: 5 V and 12 V. Each output is limited to 30 mA and includes the required boost-converter support components, decoupling, filtering, and output current-limiting stages. The design target includes schematic completion plus PCB/layout feasibility and manufacturability review."

I chose a 4-layer layout as the safer default for this power board: top and bottom for routing, one solid ground plane, and one internal power layer. That gives cleaner return paths and better noise control around the two switching regulators.
