Heat as a gift, not a blaze.

He stole fire for the build. Stroytermos keeps the warmth inside the wall.

Ten letters. Fire that stays after the theft.

Hint: rearrange “home erupts.” The product holds heat when the joke stops needing sparks.

Ember that means “hold the line.”

Keep the glow and the grit; only what settles behind them will change.

You felt the heat before the name.

When Stroytermos steps out, this page becomes the site office. Until then: wry about fire, serious about staying warm.
