 * Sonda — docs theme
 *
 * Sister to the Modern Network Observability hub and the AutoCon5 workshops:
 * shared layout DNA, Inter + JetBrains Mono. Sonda's own palette:
 *   Sunrise — midnight navy + warm coral. The dominant surface is deep
 *   ocean (slate-900 → blue-900); the accent is dawn light hitting the
 *   surface (orange-500/300). Coral lowers saturation vs. the earlier
 *   lime accent so dark-mode code surfaces read editorial, not console.
