/**
 * industries.css — Industries page specific styles
 * Elevated to match the approved home design language:
 *   - dark blueprint hero header with image-set() background wash
 *   - bone-deep "ground" hosting elevated navy tiles (pillar-card depth)
 *   - 3D illustrations served full-colour (no destructive filter)
 *   - copper hairline, dual-layer shadow, hover lift, serif index numeral
 * Reuses global classes/tokens; no shared files touched.
 * Depends on: tokens.css, base.css, layout.css, components/*.css
