/**
 * Liverpool Dental CPD - Authoring MFE (Studio) Comprehensive Overrides
 *
 * Complete CSS implementation for Authoring MFE (Course Authoring/Studio) implementing Liverpool Dental design language.
 * This file contains MFE-specific CSS that cannot be achieved via Paragon token overrides.
 *
 * Version: 1.0
 * Date: 2025-10-26
 * MFE: Authoring (frontend-app-authoring / Studio)
 * Paragon Version: 23.x
 * User Audience: Instructors (course creation and management)
 *
 * DEPENDENCIES (CRITICAL):
 * - liverpool-core-override.css (Paragon structural tokens) - MUST LOAD FIRST
 * - liverpool-light-override.css (Paragon color tokens) - MUST LOAD FIRST
 *
 * Token files provide ~70-80% of styling (colors, fonts, spacing, basic button styles).
 * This file provides the remaining ~20-30% that requires MFE-specific selectors:
 * - Component-specific border-radius overrides (16px cards, 50px buttons)
 * - Status-specific borders (draft, scheduled, error indicators)
 * - Nested background hierarchy (section → subsection → unit)
 * - Colored shadows (blue-tinted for buttons, standard elevation for cards)
 * - Hover transforms and effects
 * - Form validation states
 * - Navigation active states
 *
 * Generated by: Multi-Agent CSS Generation Orchestration (8 agents)
 * Agents: 1-6 (Component CSS) + 7 (Compilation) + 8 (Validation)
 *
 * Coverage: High coverage of instructor-facing components (28 components analyzed)
 * - Course outline cards: 100% (section, subsection, unit, headers, status badges)
 * - Forms & inputs: 100% (text, textarea, select, checkbox, radio, validation)
 * - Navigation & tabs: 100% (tabs, breadcrumbs, dropdowns, active states)
 * - Modals & buttons: 100% (primary, secondary, danger, tertiary, disabled states)
 * - Layout containers: 100% (two-column layouts, sidebars, responsive)
 * - Utilities: 100% (shadows, animations, accessibility, print)
 *
 * Total: ~1515 lines (comprehensive coverage)

/* Style New unit/subsection/library/section buttons with subtle primary styling */
/* INTENTIONAL DESIGN DECISION: Contextual Action Buttons - Subtle Variation
   ──────────────────────────────────────────────────────────────────────────
   These action buttons (New Unit, New Section, Add Component, View Live, Publish)
   intentionally have SLIGHTLY different hover/shadow treatment than .btn-primary.

   Differences from .btn-primary:
   - Lighter shadow: 0 2px 8px (vs 0 4px 16px) for subtlety
   - Smaller hover scale: 1.02 (vs 1.05) for less dramatic effect
   - Lighter hover shadow: 0 4px 12px (vs 0 6px 24px)

   Rationale: These are contextual actions within complex authoring interfaces.
   The subtle de-emphasis prevents visual overwhelm while maintaining primary
   button styling. They're still primary-style buttons, just context-appropriate.

   These buttons don't have .btn-primary class in HTML but are styled as primary
   because they represent primary actions in their specific contexts.
