Neon palette
Fennel Square
Five neon stops with room to breathe — #004b1f grounds, #317443 and #4d8f5c do the talking, #659c70 softens, #80b88b lifts. The tetradic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA as a text pair.
