/* ============================================================================
   PRAVAHA TOKENS — FITCO Design System v4
   Version 4.1.0 | 2026-07-07 | Split from pravaha.css (v70 -> v71 breakaway)
   This file carries ONLY custom-property definitions (plus ::selection).
   It is enqueued globally and is inert: token definitions cannot collide
   with any page bundle. All color truth lives HERE and only here.

   Rule-level layers moved to:
   - css/pravaha-components.css  (.p-* component library, conditional)
   - css/fud-editorial.css       (.fud-v1 + knowledge home scopes, conditional)
   Hard rule: no hex codes outside this file. Pages consume var(--p-*).
