/* Leon Environmental Services
   ---------------------------------------------------------------------------
   Colour strategy: #007320 is the LOGO's ink, sampled from the wordmark. It is
   a fully-saturated hue (HSL 137 100% 23%) — legible as ink across a 384px
   wordmark, overbearing as a 1440px background. So it is used ONLY as ink:
   logo, links, small functional marks. Large dark areas use desaturated
   neutrals (graphite / pine) that carry a green undertone without the volume.
   Every foreground/background pair below is checked against WCAG AA. */
