/*
 * IronVale Resources — Pilbara Heat
 * Bold industrial aesthetic for a mid-tier WA iron ore producer.
 *
 * Direction:
 *   - Dark slate background like ore in shadow
 *   - Rust-red and ember-orange accents (heated metal)
 *   - Hi-vis yellow as a safety/CTA accent
 *   - Bold uppercase display typography (Anton)
 *   - Body in characterful sans (Karla)
 *   - Monospace for stats and data (JetBrains Mono)
 *   - Asymmetric grids, sharp edges, big numbers as visuals
 *   - No rounded corners — everything is geometric
