/* OmniGuard design tokens - DSYS-1 - omni:design_system:v1
   THE single source of colour / type / space / radius / elevation / motion for
   omniguardlabs.com AND provewall.com. Raw colour values are allowed ONLY in this
   file; ops/design_gate.py turns any raw hex/rgb/hsl elsewhere RED.
   Palette measured from openzeppelin.com computed styles 2026-10-05
   (docs/research/COMPETITOR_SECURITY_SITES_SEO_2026-10-05.md sections 7-8).
   Brand is white-first: dark mode inverts SECTION tokens only, never the accent. */
