 * DrupalX NASA mirror — Apple-inspired space editorial design.
 *
 * Design tokens:
 *   Space palette: deep indigo → cosmic purple gradient for heroes
 *   Surface: pure white with subtle elevation shadows
 *   Typography: system-ui stack, tight tracking on display, relaxed on body
 *   Radius: 16/20/24px for cards, 999px for pills
 *   Motion: 200ms ease for hover, subtle translateY lifts
