Text to Image Prompt [3/3]: Isometric three-dimensional illustration of a project roadmap shown as five stacked material tiles climbing a staircase, each tile a different surface: brushed aluminium, frosted translucent glass, matte cork, glossy ceramic, and soft knitted wool.

A small label plate sits on each tile reading "Discovery", "Prototype", "Beta", "Launch", and "Scale". A thin ribbon arrow winds up the steps. Muted teal accent, soft even lighting so each material's sheen reads distinctly.
