Chinese traditional colors as DeepSeek Harness theme pack

Key features

• The ground is not "the traditional color, lightened"
• it is a different material.
• Light grounds sit at L ≈ 0.963–0.971: off-white rather than white, which is what leaves room for a raised surface above them.
• The sidebar and message bubbles are the anchor color itself, undiluted by paper, held inside a band of 1.25–1.55 contrast against the paper so the wash can neither disappear nor harden into a slab.
• You recognize which traditional color you are in by the bubbles, not by the background.
