/*
 * ==========================================================================
 * LESSON STUDIO — COMPONENT STYLES
 * ==========================================================================
 *
 * Phase 4I-2, Session A: Buttons, Badges, Forms, Flash Messages
 *
 * STRATEGY: Override Bootstrap's existing classes using our design system
 * tokens. Templates keep their current class names (btn-primary, badge,
 * form-control, alert-success, etc.) — the visual transformation happens
 * purely through CSS. Zero template changes required.
 *
 * LOAD ORDER in base.html:
 *   1. bootstrap.min.css
 *   2. bootstrap-icons.css
 *   3. design-system.css      (tokens + utilities)
 *   4. components.css          (THIS FILE — overrides Bootstrap)
 *
 * IMPORTANT: This file must load AFTER both Bootstrap and design-system.css.
