Real combustion physics: white-yellow inner core transitioning through orange and deep red to wispy blue-grey outer tips. Turbulent flame tongues surge upward with natural random motion. Dense dark smoke billows in heavy rolling columns, curling upward — charcoal and near-black with faint translucency at edges. Firelight self-illuminates from below with warm amber-orange cast. Dramatic upward rim from intense heat source underneath. Background: deep charcoal haze with faint ember glow — not pure black. Cinematic fire photography quality. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the flame-and-smoke material, the combustion glow and the cast light. FALLBACK MATERIAL: if the font carries no material of its own, render the letters ablaze — a white-yellow core through orange to deep red flame tongues with dark rolling smoke and warm self-illumination from below. COLOR PRIORITY: keep the font's own colors if specified; otherwise the natural fire spectrum of amber, orange and deep red. A subterranean Potosí mine cavern opens into a monumental infernal chamber: wet black rock walls, jagged silver-veined stone, collapsed timber braces and a distant shaft disappearing into charcoal haze. Render “LA CUEVA DEL DIABLO DE POTOSI” as the sole heroic title, arranged in three centered tiers with “DEL DIABLO” dominant, spanning roughly 78% of the frame. The letters are consumed from within by real combustion: brilliant white-yellow cores bloom through orange and deep crimson flame, while tall turbulent flame tongues tear upward from edges and counters. Dense near-black smoke rolls from the title in heavy curling columns, translucent at its ash-grey rims, merging into the cave ceiling. A furnace-like glow rises from below, casting amber highlights across damp obsidian textures and long violent shadows into the tunnel. Fine ember sparks spiral upward through the composition; heat distortion ripples visibly above every word. Keep the surrounding space almost black but never empty, with faint red mineral glow and drifting soot revealing depth. The mood is forbidden, mythic, claustrophobic and cinematic: an underground legend awakened by fire.
