/* ==========================================================================
   Demo 06 — Consultant  ·  demos/06-consultant/css/theme.css

   Design rationale
   ----------------
   Serious and results-forward. Graphite ink with a single amber signal
   colour, tight rhythm and data everywhere: a KPI band, a numbered
   engagement process and case studies stated as figures. Layout archetype A
   (two-column hero) but data-led rather than code-led, so it reads nothing
   like demo 01 despite sharing the skeleton.

   ISOLATION CONTRACT
   Scoped to :root (token values) or .rp-demo--consultant only.
