A dense, shimmering colony of microscopic extremophile microbes clinging to a glowing mineral fracture deep underground. The delicate bio-filaments extract chemical energy directly from hot, mineral-rich hydrothermal fluid seeping through jagged basalt rock. Composition: close-up, macro close-up, featuring Macro shot focusing tightly on the undulating microbial filaments occupying the center of the frame against rough, shadowed rock textures. Scientific details: Chemoautotrophic microbial filaments adhering to sulfide-rich mineral veins, surviving without sunlight in hyper-heated subterranean niches. Color palette: Deep obsidian black, Amber geothermal glow, Pale translucent white. The complete visual composition must sit comfortably inside the canvas with generous clean white/off-white negative space visible on all four sides: left, right, top, and bottom (target 8-12% margins, minimum 6%). The main illustration must occupy maximum 80% canvas height and 84% canvas width. Never stretch vertical geological columns, shafts, planetary spheres, magma conduits, or tall objects to touch the top or bottom boundaries; scale the entire illustration down inside the safe central canvas. Keep all important elements fully inside the safe frame. Nothing may touch or cross any canvas edge. Do not crop the primary subject. Do not use edge-to-edge artwork. Do not fill the entire frame with background scenery. hand-drawn 2D explainer cartoon illustration, thick clean black outlines, simplified readable forms, flat cel-style colors, soft minimal shading, clean educational YouTube illustration, clear focal hierarchy, no photorealism, no 3D rendering, no typography, no text, no watermarks
