/* Design tokens: commodities-gold. Refined, deep neutral (charcoal) with a gold accent on warm ivory paper.
   Gold is a FILL or BORDER only, never small text on light. Links use deep bronze for contrast.
   Contrast (hand-calculated, AA): ink on paper ~16:1, bronze link on paper ~7:1, paper on charcoal header ~15:1,
   ink on gold fill ~7:1, gold on charcoal ~8:1, error-700 on white ~6.5:1, success-700 on success-bg ~6:1.
   Type: system stacks, serif headings for a refined feel, 1.25 scale. Names such as --color-navy-* are what the
   shared layout CSS reads: here navy-800 is charcoal and navy-700 is bronze. */
