/**
 * DataIntellit — Utility & Component Supplements
 * Adds the Bootstrap-style spacing / display / text-color utilities referenced by the
 * static markup but not declared in the core design system, plus the small interactive
 * components (OS badge, FAQ accordion, ROI calculator, pricing badge, reveal helpers).
 * Loaded after style.css so it composes cleanly on top of the token palette.
