/*
 * Design Brief: Auronix ← inspired by https://www.aurionx.ai/
 *
 * Structure: hero-centered-stats → problem-statement → capability-grid →
 *            three-ways-pricing → industry-grid → use-case-strip →
 *            comparison-split → cta-band → footer-multi-column
 *
 * Hero: centered typography, grid background, badge pills, stat row
 * Style: neo-brutalist monochrome — black/white, zero radius, offset shadows
 * Fonts: Inter (sans) + Space Mono (labels/stats)
 * Motion: fade-up reveals, brutal shadow hover lift, no orbs/gradients
