Thistled Courtyard
Five nebula stops with room to breathe — #004b62 grounds, #007597 and #3190b3 do the talking, #559ebc softens, #71bbda lifts. The split-complementary bones keep it coherent across hotel key cards and lobby signage in one system. The darkest and lightest stops clear AA as a text pair.
