/* =====================================================================
   BULLIONPORTFOLIO — "VAULT NOIR" THEME
   Drop-in replacement for style.css. Same selectors throughout, so no
   HTML/Vue template changes are required — only the values changed:
   color palette (pastel gold / silver + a muted crimson accent that
   replaces the old --red for negative/sell/danger states), display
   typography for the big numbers, and a few small contrast/letter-
   spacing refinements. Structural rules (layout, spacing, grid) are
   carried over unchanged from the original stylesheet.
