   Palette is derived from the logo SVG fills (assets/unityroot-logo.svg):
     rgb(135,147,63)  #87933F  leaf olive   — the dominant foliage colour
     rgb(70,192,207)  #46C0CF  teal         — the second leaf colour
     rgb(243,173,43)  #F3AD2B  amber        — the flame leaf
     rgb(193,50,52)   #C13234  crimson      — the accent leaves
     rgb(31,30,28)    #1F1E1C  warm ink     — the tree and figures
   Tints/shades below are ramps built off those five so that text-weight
   colours clear WCAG AA while the pure logo hues stay for graphics.
