/* BlackGrid OS — shared design system for Kryptaris / Caduceon / Oraculum.
 *
 * Same warm-black foundation as the marketing site (#0a0a0a + #f4f3ee +
 * IBM Plex Mono + Helvetica), but reorganized for product-console density:
 * sidebar + main + right panel layout, dense panels, monospace data.
 *
 * Each product layers a `--accent-2` color variable on top for differentiation:
 *   Kryptaris : cyan-tinted #9bb1f5 (data layer)
 *   Caduceon  : green-tinted #8ac8a3 (deployed/shipped)
 *   Oraculum  : violet-tinted #b59ce5 (cognition)
