You can see how all the power supply connections use large traces or copper pours. The AWG doesn’t have high current requirements, but the board house doesn’t give you a discount for using less copper, so you might as well opt for large (= low-resistance, low-inductance) traces if you have the room.
The decoupling capacitors (C4, C5, C6, C7, C9, C10, C11) are arranged around the perimeter of the chip, very close to their respective power pins and to the vias that connect the caps to the internal planes. Notice how the smaller cap is always closer to the power pin; this is because we rely more on the lower-value capacitor for high-frequency bypassing, and thus the first priority is minimizing the inductance and resistance between the smaller cap and the pin.
