/* Old Gold Standard - site stylesheet.
   Palette: old gold (#CEB888) and black. Contrast pairs checked with the
   WCAG relative-luminance formula before use (see src/site.py build notes):
     black #1a1a1a text on white bg .......... 17.40:1
     dark gold-brown #5a4712 link on white ...  8.96:1
     old gold #CEB888 nav text on black header 10.84:1
     off-white #f0ece0 text on near-black bg .. 16.46:1
     old gold #CEB888 accent on near-black bg . 10.03:1
   Old gold itself (#CEB888) is NEVER used as body text or link color on a
   light background - it measures 1.94:1 on white, well under the 4.5:1
   minimum. It is used only as an accent/border and as text on dark
   backgrounds, where it clears AA comfortably. */
