High resolution, wide horizontal medical infographic illustration showing tissue healing progression inside a fibrous scaffold, left to right.

Background is a clean gradient panel with a rounded rectangular frame, subtle drop shadow, and a neutral clinical gray backdrop.

Main illustration is a long continuous band of pale blue and white scaffold fibers transitioning into integrated tissue.

Left third: dense chaotic scaffold mesh with many red blood cells (small red biconcave discs) and several immune cells (purple and yellow spheres) embedded between fibers.

Middle third: scaffold becomes slightly less dense and more organized, with spindle shaped fibroblasts (pink elongated cells) aligned along fibers and increased extracellular matrix.

Right third: mature tissue with thicker aligned pale pink fibers and branching red blood vessels (arterioles) embedded through the tissue, scaffold strands thinning and fading.

At the top, include three color coded header tabs with circular thumbnails and exact text:
Left tab, orange theme: "0-3 Days" on the top line and "Inflammatory Response" beneath it.
Middle tab, magenta theme: "1-45 Days" on the top line and "Cellular Proliferation" beneath it.
Right tab, blue theme: "30-300 Days" on the top line and "Maturation & Remodeling" beneath it.

Typography is modern, clean, perfectly spelled, and does not overlap the main illustration. Soft clinical lighting, realistic restrained colors, no decorative flourishes, no branding, no watermark, no logo.
