/**
 * Koushik Tours & Travels™ — Production Base Stylesheet
 * ---------------------------------------------------------------------------
 * Copyright © 2026 Mayank Chawdhari.
 * Developed, hosted & managed by Mayank Chawdhari under Privonix Technologies.
 * Website: https://www.koushiktravels.in/
 * Technology Partner: https://www.privonix.in/
 *
 * PURPOSE
 * -------
 * Central design-system stylesheet for Koushik Tours & Travels.
 * This file contains the global reset, typography, color tokens, accessibility
 * defaults, form controls, reusable icon representations and all 13 button
 * variants required by the modular monolith architecture.
 *
 * DESIGN SYSTEM
 * -------------
 * Font    : Tenor Sans
 * Theme   : Onyx & Charcoal
 * Ratio   : 60% White / 30% Dark Neutral / 10% Premium Accent
 * Accent  : Burnished Copper Orange (#C96F32)
 *
 * PRIMARY USAGE
 * -------------
 * Include this file once from the central website shell/modules layer:
 *   <link rel="stylesheet" href="/Assets/Modules/base.css">
 *
 * MODULE RULE
 * -----------
 * Keep page-specific styles out of this file. Page/content CSS belongs with
 * the page module/content file. Shared primitives belong here.
 *
 * VERSION
 * -------
 * v1.0.0 — 18 August 2026
 * Initial production base for the Koushik Tours & Travels website.
 *
 * CHANGE HISTORY
 * --------------
 * v1.0.0 — 2026-08-18
 * - Replaced generic theme tokens with an Onyx & Charcoal luxury system.
 * - Locked primary canvas to pure #FFFFFF.
 * - Added 60/30/10 color architecture.
 * - Added Tenor Sans typography tokens.
 * - Added five reusable icon representation types.
 * - Added all 13 button variants.
 * - Added dedicated bordered and dotted icon-only controls.
 * - Added accessibility, focus, reduced-motion and form defaults.
