/**
 * Academia Buenos Aires - Design System
 * Version: 2.0 - Complete with all page components
 *   2026-06-24: --font-family-* set to Inter (the FIGMA design font) and applied
 *     site-wide via a !important override at the end of this file (the font is
 *     otherwise controlled by GeneratePress). Inter is enqueued in functions.php.
 *   2026-06-22: hero gradients use background-image (not the `background`
 *     shorthand) so they no longer reset background-size/position on the
 *     image-based homepage hero (fixed the cropped mobile hero at the root;
 *     lets home-sections.css drop its !important)
 *   2026-06-20: added global .badge-yellow (course-card category/"Most chosen" badge) so it works outside the homepage (e.g. the All Courses page)
 * 
 * Complete CSS Custom Properties based on Figma Design Tokens
 * This file contains all colors, typography, spacing, and component styles
 * for the Academia Buenos Aires multisite.

   FIGMA DESIGN FONT (Inter)
   The font family is controlled by GeneratePress (parent theme), so the
   --font-family-* variables alone don't apply. This override sets Inter on the
   text-bearing elements with !important to win over GP's typography CSS.
   Inter itself is loaded via wp_enqueue_style('academia-inter') in functions.php.
   Icon fonts (.fa, .material-icons-*) target their own elements and are unaffected.
