   @cloudingenium/design-tokens — CloudIngenium (plain :root vars twin)
   Dev / cloud / tech / internal IT + observability. Indigo-violet primary signals tech/cloud mood, cyan accent echoes terminal/data aesthetic.
   Generated from tokens.source.json — do not edit directly.

   Browser-parsable twin of cloudingenium.css: every brand token under a
   plain :root block (NOT the Tailwind at-rule, which is parser-invisible).
   Link this directly from non-Tailwind consumers (e.g. Blazor _Host.cshtml).
