/*
 * Black Marble — modern luxury in black marble and brass.
 * Two real marble textures (CC0, img/CREDITS.md), both seamless tiles:
 *   marble-nero-soft.webp      black Portoro with brass veins, veins as a transparent layer over --inv-background (dark stone of the variant)
 *   marble-calacatta-soft.webp warm Calacatta, shading as a transparent layer over --inv-surface (light stone of the variant)
 * Sections alternate dark / light by their order on the page (nth-child), so hidden sections never break the
 * rhythm; the closing is always dark. Blocks inside a section take the opposite stone (.bk-inv, countdown tiles,
 * bank cards). Every color in a section comes from the tone variables (--t-*).
 * Brass = fine metal inlay: hairline frames shifted off photos, inlay rules with a small ring, a round plaque.
 * Fonts: var(--inv-font-display) script for names only, var(--inv-font-heading) for titles, Montserrat for text.
 * Colors: --inv-primary (brass), --inv-accent (brass highlight), --inv-deep (dark brass, labels on light stone),
 * --inv-label (brass on dark stone), --inv-background, --inv-text, --inv-surface, --inv-ink.
