 * DEPLOYMENT:
 * ===========
 * Use this single file instead of loading three separate files.
 * Configure your Tutor plugin to serve this CSS after Paragon's base CSS.
 *
 * Load order:
 * 1. Paragon core.min.css (CDN)

   NOTES & DOCUMENTATION
   ============================================================================ */

/*
 * IMPORTANT: This file contains ONLY structural tokens that can be overridden
 * via Paragon's --pgn-* CSS custom properties. It does NOT include:
 *
 * - Colors (those are in liverpool-light-override.css)
 * - Letter spacing (Paragon has no tokens; apply in MFE CSS)
 * - Shadows (Paragon has component-specific only; define scale in MFE CSS)
 * - Gradients (not tokenizable; define in MFE CSS)
 * - Transform effects (not tokenizable; define in MFE CSS)
 *
 * PARAGON VERSION: 23.14.9
 * All token names verified against Paragon CDN CSS analysis (Agent 1).
 *
 * WHAT THIS FILE CONTROLS:
 * ✅ Typography (font family, sizes, weights, line heights)
 * ✅ Border radius (base scale + component-specific)
 * ✅ Button border radius (pill shape)
 * ✅ Transitions (duration and easing)
 * ✅ Spacing (base unit)
 *
 * WHAT REQUIRES MFE CSS:
 * ❌ Letter spacing for Display, H1, H2, Buttons, Counter, Overline
 * ❌ Liverpool shadow scale (shadow-xs through shadow-xl)
 * ❌ Liverpool custom spacing (space-7: 40px, space-12: 96px, space-16: 128px)
 * ❌ Button padding (1rem × 2.5rem) - if Paragon tokens don't work
 * ❌ Card padding (2rem all sides)
 * ❌ Form input padding (0.75rem × 1rem)
 * ❌ Mobile typography scaling for H2-H6 (media queries)
 * ❌ Custom line heights (1.2, 1.3, 1.4, 1.6) for specific elements
 * ❌ Text transform (uppercase for buttons and overlines)
 * ❌ Gradients (primary, navy, decorative)
 * ❌ Box shadows (elevation system and colored shadows)
 * ❌ Hover transforms (scale, translate)
 * ❌ Backdrop filters (glassmorphism)
 *
 * TESTING CHECKLIST:
 * After loading this file, verify:
 * 1. ✅ Typography uses Poppins font family
 * 2. ✅ Body text is 16px (not 18px)
 * 3. ✅ Headings use correct sizes (H1: 40px, H2: 32px, H3: 28px, H4: 24px, H5: 20px, H6: 16px)
 * 4. ✅ Headings use SemiBold weight (600)
 * 5. ✅ Buttons have pill-shaped border radius (50px)
 * 6. ✅ Cards have 16px border radius
 * 7. ✅ Form inputs have 8px border radius
 * 8. ✅ Transitions feel slightly slower (300ms vs 200ms)
 * 9. ✅ Overall UI has Liverpool's modern, friendly aesthetic
 *
 * MAINTENANCE:
 * When updating Paragon version:
 * 1. Run Agent 1's token extraction methodology on new Paragon version
 * 2. Compare token names against this file
 * 3. Verify no breaking changes to token structure
 * 4. Test all overrides still work as expected
 * 5. Update version number in header
 *
 * NEXT STEPS:
 * After loading liverpool-core-override.css:
 * 1. Load liverpool-light-override.css for color overrides
 * 2. Load MFE-specific CSS (liverpool-learning.css, etc.) for enhancements
 * 3. Test across all MFEs (Learning, Authoring, Gradebook, Account, Profile)
 * 4. Validate WCAG AA accessibility compliance
 * 5. Gather stakeholder feedback and iterate

/* INTENTIONAL DESIGN DECISION: Hero Button Treatment
   ──────────────────────────────────────────────────────────────────────────
   This "Next" navigation button intentionally differs from standard .btn-primary
   to provide extra visual emphasis as the primary forward-navigation action.

   Differences from standard primary button:
   - Gradient background (vs solid) for premium feel
   - Uppercase text transform for emphasis
   - Slightly larger padding (1rem vs 0.75rem)
   - Different shadow treatment

   Rationale: The main "Next" CTA deserves hero treatment to guide learners
   through course content. This is a intentional design exception.
