   Contrast checked with the WCAG relative-luminance formula (not eyeballed):
   - gold  #D1AF60 on near-black #1A1A1A  -> 8.30:1  (use for text on dark bg)
   - gold  #D1AF60 on off-white #F9F9F9   -> 1.99:1  (FAILS — never use as text on light bg)
   - green #6CA26E on near-black #1A1A1A  -> 5.83:1  (use for links/accents on dark bg)
   - green #6CA26E on off-white #F9F9F9   -> 2.84:1  (fails even large-text AA — do not use as text on light bg)
   - dark gold #8C6B24 on off-white       -> 4.70:1  (passes — use for gold text/links on light bg)
   - dark green #3B6A3E on off-white      -> 6.01:1  (passes — use for green text/links on light bg)
