Ember Forge · 余烬锻造

Charcoal steel surfaces, barely lit, and a spray of amber sparks caught mid-flight — the illustration keeps the fire itself out of frame, so what you get is heat implied by light: #ff9e3d embers against near-black, a faint glow gradient low in the scene, brushed-metal texture underneath it all. It's the darkest artwork in the set, and the discipline of showing sparks but never flame is what keeps it usable behind text.

Save it for the heavy sessions — the migration you've been putting off, the bug that has survived three attempts, release night. It was drawn to sit behind the Ember Shift theme and shares its exact ember accent, so the pair reads as one forged object; Gruvbox Dark's amber also settles in well. In a fully dark room the sparks become the brightest thing you can see, which on the right night is precisely the mood.
