/* ============================================================================
   CatalystIQ — "Violet Ledger Interface"
   Transcribed from DESIGN.md (source: relevanceai.com). Tokens are normative
   values from that spec; do not invent colours outside this block.

   Guardrails from the spec, kept as comments where they are easy to violate:
     • The violet gradient is corner-rationed (~3% coverage per wash). Never a
       full-bleed fill; the page stays white-dominant.
     • The nav CTA radius is 4.8px — distinctly squarer than pill actions. It is
       NOT 9999px.
     • Secondary/ghost buttons stay grayscale. Violet is for the gradient CTA
       family only.
     • Elevation comes from hairline borders and soft multi-layer shadows on
       white — never darkened panels or heavy drop shadows.
     • No serif and no monospace face anywhere. Sora (display) + Inter (all
       other roles, including data).

   One documented extension: this spec describes a marketing site, so it defines
   no negative/severity colour. A pipeline console needs semantic status. The
   additions are marked below and kept to the minimum the data requires.
