/**
 * BotPiper Design System
 * Version: 1.2.0
 * Last updated: 2026-02-23
 * 
 * Changelog:
 * - v1.2.0: Expanded utility layer — full framework-agnostic utility classes
 *           (spacing, flex/grid, sizing, typography, color, border, position,
 *           overflow, cursor, opacity, transition). Dev team can copy class
 *           names directly into React/Vue/any framework. Flat selectors only.
 * - v1.1.0: Added sortable tables, pagination, table filters, expandable rows
 * 
 * This is the single source of truth for all design tokens and base components.
 * All BotPiper surfaces (marketing, account portal, dashboard, admin) import this file.
 * 
 * NEVER hardcode hex values in component CSS — always use custom properties.

   9f. Colors (text, background, border)
   9g. Borders & Radius
