The canvas is 800x600 — square, not rectangle. Shapes should fit cleanly within it without stretching or distorting anything.

Draw a gradient background that transitions from dark to light across the bottom third of the canvas. The top two-thirds are solid color: blue (#2a2a5a) at the edge, grey (#111) in the middle, black (#000) at the far right where the boundary meets the side panel.

In the center, draw a lever that curves upward from a horizontal line at y=60. The handle is a semicircle with radius 15 drawn on its outside edge — but don't fill it in yet so people can see how heavy it is just by touch.

Around the edge of this central area, draw 12 small circles each about 12 units wide and centered along the x-axis from -5 to +17. These represent people whose voices are being audited. Their base radius increases over time according to a simple cosine function — but don't show them pulsing yet.

At 0:35, when t=6: The canvas is completely drawn. The background gradient has fully saturated; the people's bases have grown to their full height; and the lever's hand has stopped moving upward because we've hit our target weight for this iteration of the simulation.
