Candle Flame Simulator (2D)

This 2D simulator renders a single candle with a working melt-and-draft model underneath: a wick-length slider sets how much wick is exposed above the wax pool, which drives both flame height and how fast the candle melts, while a draft slider bends and destabilizes the flame the way a passing breeze does — strong enough draft snuffs the flame out entirely. Live readouts track wax remaining, flame height, estimated burn time left, and the running drip count as the melt pool overflows down the candle's side. Use Blow for a one-off gust, Relight after the flame goes out, and New candle to reset the wax to full height.
