A full-bleed wall of rising fire, drawn from noise alone.

A GLSL fragment shader that paints fire in two dimensions. A fuel field burns from the bottom edge to a different height in every column, and fractal noise scrolling downward erodes it, so the tongues read as flame rising and swaying more the higher they climb. Heat runs through a five-stop ramp from ember red to a white-hot core over a dark ground, in the page's own primary and secondary where a design system is set and a fire palette where it is not. Runs entirely on the GPU at full-viewport scale; a dramatic hero backdrop for forge, grill, launch and heat-themed pages.
