 * Hero section styling.

 * alongside this stylesheet as `hero-bg.png`. It provides a modern, abstract
 * technology feel with dark blue and purple tones. The background is set to
 * cover the entire hero area and remain centered on all screen sizes. We
 * override the solid colour from the previous version.
