/**
 * Garment Printer — Hero Three-Zone (v3.8 SB7 layout)
 * Ported from index-v3.html (lines 134-368) into theme architecture.
 *
 * Geometry:
 *   Desktop (>=1024px): two rows, equal height. Top = Zone A full-bleed.
 *                       Bottom = Zone B (2/3) + Zone C (1/3).
 *   Tablet (<1024px):   single column stack, fixed aspect ratios.
 *   Mobile (<600px):    Zone A switches to 4:5 portrait (art-directed).
 *
 * Per-zone tints:
 *   Zone A — cream (ground-warm)
 *   Zone B — accent-tinted (eucalyptus)
 *   Zone C — dark ink
 *
 * Branding tokens are scoped to .hero-three-zone so this section can ship
 * before the theme's global Eucalyptus tokens land. Once theme.css adopts
 * these values, the locally-scoped block can be removed (see PORT-NOTES.md).
