**Dynamic Wave Frame & Silhouette Graphics:**
- Sweeping along the absolute lower margin boundary: A dynamic arrangement of smooth flowing curved royal blue wave abstract ribbons highlighted with fine shiny gold outer strokes.
- Floating right above the blue wave ribbons: A semi-translucent light blue silhouette overlay illustration (hình bóng mờ) depicting a happy healthy community of citizens, running athletes, and children holding hands, positioned against a faint modern city skyline horizon and a structural bridge mesh graphic.
- On the lower-left corner: A circular public health vector emblem badge decorated with green laurel leaf branches on the sides.
**Official Bright Gradient Background Concept:**
- The background features a clean, professional soft gradient surface shifting from vibrant light blue at the outer frames to a bright radiant white center. Several minimalist white peace doves (bồ câu trắng) are depicted flying gracefully on the left and right sides under soft glowing light rays.
