   Differentiates Aurum from Nile Precious Metals (black + champagne gold
   + Cinzel + gold block CTA). Audit: projects/aurumgoldtraders/audit-2026-11-13.
   Method: invert the colour TOKENS so the existing band rhythm survives —
   dark canvas -> warm stone, paper bands -> deep-forest ink bands — then
   override the few hard-coded dark values. Every text pair checked >= 5:1.
   To revert: delete from this banner to end of file + restore Cinzel preload.
