/*
 * Black Marble — rich, glossy marble with gold veins and gold geometric frames.
 * The marble is pure CSS: soft clouds (radial gradients), pale veins and thin gold veins
 * (thin rings of large ellipses + hairline linear gradients), a diagonal gloss, and a light
 * SVG grain on top. Playfair Display + EB Garamond + Great Vibes + Montserrat.
 * Colors come from the variant (--inv-primary, --inv-accent, --inv-background, --inv-text,
 * --inv-surface, --inv-deep, --inv-vein, --inv-label, --inv-ink). All template classes start with "bk-".
