/*
 * VADIRA — Elegant Monochrome Design System
 * Inspired by Apple & Cursor: quiet, precise, high-contrast, generous spacing.
 *
 * Palette (strict monochrome):
 *   #000000  base black
 *   #0A0A0A  surface
 *   #0F0F0F  raised surface
 *   #141414  hover surface
 *   #1E1E1E  border / hairline strong
 *   #2A2A2A  border strong
 *   #6E6E73  muted text
 *   #A1A1A6  secondary text
 *   #F5F5F7  near-white text
 *   #FFFFFF  white
 *
 * Type system (thematic):
 *   Display / headings : "Space Grotesk"  (modern, geometric, techy)
 *   Body / UI          : "Inter"          (clean, neutral)
 *   Numbers / hashes   : "JetBrains Mono"  (blockchain / crypto feel)
