🕯️ Realistic Candle Burning in a Dark Room: 3D Wax, Flame and Smoke Lab

A candlelit study at dusk: a hand-poured candle in a brass dish on an oak desk, with a bookshelf, a window onto a twilight village, an armchair and a crackling fireplace. Light and extinguish the candle, open the window to make the draught lean the flame, and watch the wax melt, pool, run and set. Real equations for burn power, flame height, buoyant plume speed, capillary wick rise, melt-pool balance and the colour of a 1500 K glow, with an honest physics-versus-visual table and a fire-safety note.
