Flickering Square
Five petrichor stops with room to breathe — #004c4f grounds, #00777c and #319297 do the talking, #549fa3 softens, #71bcc0 lifts. The tetradic bones keep it coherent across national-park posters with layered mountain silhouettes. The darkest and lightest stops clear AA for large text.
