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. Cinematic dark poster built around the exact text “COV14” as the single monumental hero, centered and spanning roughly 68% of the frame width. Each character is consumed by physically believable living fire: an incandescent white-yellow core near the lower edges, graduating through molten gold and orange into saturated crimson, with ragged blue-grey flame tips peeling upward. Flame tongues rise at unequal heights, curling, splitting, and shedding sparks in chaotic natural motion, while the lower letter bodies retain a dense ember-red glow beneath the combustion. Thick charcoal smoke pours from the upper contours and interior gaps, rolling into layered near-black clouds with translucent ash-grey edges. An intense amber-orange firelight blooms from beneath the word, throwing a hot rim around every silhouette and dimly illuminating the smoke from below. Heat distortion visibly warps the air directly above the letters. Background is a deep charcoal-black haze, never flat black, with a faint volcanic glow low on the horizon and sparse ember particles floating upward like tiny stars. Preserve generous dark negative space around the burning word. High-contrast fire photography atmosphere: dangerous, urgent, elemental, and visually absolute.
