1. A package comprising a container having a brim, a floor, and a side wall arranged to interconnect the brim and the floor, the brim being adapted to mate with a lid to close an opening into an interior product-storage region bounded by the floor and side wall,wherein the side wall includes, in series, a base section associated with the floor, a first structural rib section, a pop-panel section, a second structural rib section, and a canopy section associated with the brim, the pop-panel section includes a frame arranged to interconnect the first and second structural ribs and at least one elastic pop panel supported on the frame for movement in a radially inward direction toward a vertical central axis of the container from an initial pre-contraction shape to a temporary hot-fill contracted shape in response to a vacuum in the interior product-storage region that develops during a hot-fill activity in which a hot fluid is introduced into the interior product-storage region to decrease the volume of the interior product-storage region without damaging the side wall of the container, the side wall has a variable wall thickness, the base section defines a first side-wall zone characterized by a first wall thickness, the first structural rib section defines a second side-wall zone characterized by a second wall thickness that is greater than the first wall thickness, the pop-panel section defines a third side-wall zone characterized by a wall thickness that is less than the first wall thickness, the second structural rib section defines a fourth side-wall zone characterized by a fourth wall thickness that is greater than the second wall thickness. 2. The package of claim 1, wherein the canopy section defines a fifth side-wall zone characterized by a fifth wall thickness that is about equal to the first wall thickness. 3. The package of claim 1, wherein the first wall thickness is about 0.025 inches, the second wall thickness is about 0.045 inches, the fourth wall thickness is about 0.050 inches, and the third wall thickness is about 0.015 inches. 4. The package of claim 3, wherein the canopy section defines a fifth side-wall zone characterized by a fifth wall thickness that is about equal to the first wall thickness. 5. The package of claim 1, wherein the frame is formed to include six circumferentially spaced-apart, oblong, endless panel borders, each elastic pop panel is coupled to one of the endless panel borders included in the frame to fill space bounded by the one of the endless panel borders to provide a monolithic third side-wall zone and the third wall thickness is about 0.015 inches. 6. The package of claim 5, wherein each elastic pop panel comprises a central dome and a ring-shaped bridge arranged to surround and mate with a companion central dome and with a portion of the endless panel border surrounding the ring-shaped bridge. 7. The package of claim 6, wherein the second wall thickness is about 0.045 inches and the fourth wall thickness is about 0.050 inches to maintain hoop strength of the first and second structural ribs during exposure of the elastic pop panels to a vacuum in the interior product-storage region produced by a hot-fill liquid in the interior product-storage region and resultant movement of each of the elastic pop panels relative to the frame from a pre-contraction shape in the radially inward direction toward the vertical central axis to assume a contracted shape. 8. The package of claim 1, wherein each of the first and second structural ribs has an annular shape, the frame has an annular shape, the third wall thickness is about 0.015 inches to maximize pliability and flexibility of the elastic pop panels, and the second wall thickness is about 0.045 inches and the fourth wall thickness is about 0.050 inches to minimize out-of-round distortion of the side wall during flexure of the elastic pop panels relative to the frame when exposed to a vacuum in the interior product-storage region. 9. A package comprising a container having a brim, a floor, and a side wall arranged to interconnect the brim and the floor, the brim being adapted to mate with a lid to close an opening into an interior product-storage region bounded by the floor and side wall,wherein the side wall includes, in series, a base section associated with the floor, a first structural rib section, a middle section, a second structural rib section, and a canopy section associated with the brim, the base section defines a first side-wall zone characterized by a first wall thickness, the first structural rib section defines a second side-wall zone characterized by a second wall thickness that is greater than the first wall thickness, the middle section defines a third side-wall zone characterized by a wall thickness that is less than the first wall thickness, the second structural rib section defines a fourth side-wall zone characterized by a fourth wall thickness that is greater than the second wall thickness. 10. The package of claim 9, wherein the first wall thickness is about 0.025 inches, the second wall thickness is about 0.045 inches, the fourth wall thickness is about 0.050 inches, and the third wall thickness is about 0.015 inches. 11. The package of claim 10, wherein the canopy section defines a fifth side-wall zone characterized by a fifth wall thickness that is about equal to the first wall thickness. 12. The package of claim 9, wherein the canopy section defines a fifth side-wall zone characterized by a fifth wall thickness that is about equal to the first wall thickness. 13. The package of claim 9, wherein each of the first and second structural ribs comprises bands of material. 14. The package of claim 9, further comprising a label arranged to surround an exterior surface of the middle section and overlie portions of the first and second structural ribs.
