/* ============================================
   DESIGN SYSTEM VALIDATION & LIMITATIONS
   ============================================ */

/*
  Nexus Design System - Implementation Status
  
  COMPLETED SECTIONS:
  ✓ Color tokens (primary, secondary, neutrals, semantic)
  ✓ Typography system (headings, body, utility text)
  ✓ Button components (primary, secondary, ghost, danger, sizes)
  ✓ Card components (basic, module, stat, case summary)
  ✓ Form elements (inputs, selects, textareas, checkboxes)
  ✓ Navigation (sidebar, top nav, nav items)
  ✓ Data tables with sortable headers
  ✓ Status badges (not-started, in-progress, completed, blocked, error)
  ✓ Loading states (skeleton, shimmer animation)
  ✓ Empty states with icons
  ✓ Accessibility (screen reader, skip link, focus management, reduced motion)
  ✓ Utility classes (display, flex, grid, spacing, text, colors, borders)
  ✓ Clinical/legal components (risk panels, evidence cards, timeline)
  ✓ Record citations with Bates numbering support
  ✓ Reviewer findings with citation tracking
  ✓ Documentation gap alerts
  ✓ Compliance status indicators
  ✓ Standard of care issue blocks
  ✓ Nexus semantic classes (clinical-fact, legal-allegation, expert-opinion)
  ✓ Responsive breakpoints (tablet ≤1024px, mobile ≤768px, small mobile ≤480px)
  
  ACCESSIBILITY COMPLIANCE:
  ✓ WCAG 2.2 AA contrast ratios for all text and UI components
  ✓ Focus indicators on all interactive elements
  ✓ Screen reader support with sr-only classes
  ✓ Reduced motion support
  ✓ Keyboard navigation ready
  ✓ Touch-friendly tap targets (44px minimum on mobile)
  ✓ Font size 16px+ on forms to prevent iOS zoom
  
  DESIGN PRINCIPLES ENFORCED:
  ✓ Clinical but warm aesthetic
  ✓ Apple-like spacing and restraint
  ✓ Litigation-ready visual hierarchy
  ✓ No generic SaaS styling
  ✓ No command-center or cyberpunk language
  ✓ Product identity: "Nexus" by LNC Nexus Technologies, LLC
  ✓ Mobile-first responsive design
  
  KNOWN LIMITATIONS:
  • Dark mode support implemented but not fully tested across all components
  • Print styles added (2026-07-09) — verify in staging environment
  • Animation effects minimal by design (can add micro-interactions if requested)
  • No CSS Grid system utilities beyond flexbox (add if needed)
  • Component states (hover, active, disabled) implemented for core components only
  • Sidebar hidden on mobile ≤480px (requires bottom nav or hamburger implementation)
  
  ASSUMPTIONS:
  • Inter font family loaded externally (Google Fonts or self-hosted)
  • Merriweather font loaded externally for serif elements
  • Fira Code/Mono loaded externally for code/citation elements
  • Icons provided via SVG or icon font (not included in this CSS)
  • Icons should be minimum 24px for touch accessibility
  
  NEXT STEPS (if needed):
  1. Verify print styles in staging environment
  2. Add micro-interaction animations (subtle hover states, transitions)
  3. Add CSS Grid utility classes
  4. Implement mobile navigation (bottom nav or hamburger menu)
  5. Add component-specific animation states
  6. Add touch gesture support for swipe actions
  
  FILES MODIFIED:
  - static/css/design-system.css (added clinical/legal components, semantic classes, responsive breakpoints)
  
  NAMING CORRECTIONS MADE:
  - All "LNC Nexus" references are consistent with brand casing
  - No "SOPSAAS" references in product-facing comments
  - Clinical terminology preferred over tactical/command-center language
  
  VALIDATION PERFORMED:
  ✓ Color contrast ratios verified (minimum 4.5:1 for normal text, 3:1 for large text)
  ✓ Focus states present on all interactive elements
  ✓ Semantic class naming follows Nexus conventions
  ✓ Component structure supports litigation workflows
  ✓ No duplication of existing CSS rules
  ✓ No breaking changes to existing components
  ✓ Responsive breakpoints tested for layout integrity at 320px–1024px
  ✓ Touch targets minimum 44px for accessibility
  ✓ Form inputs 16px+ to prevent iOS zoom
  
  RISKS OR INCOMPLETE AREAS:
  • Dark mode: Test all clinical components in dark theme on mobile devices
  • Print styles: Implemented but not tested in staging environment
  • Mobile navigation: Sidebar hidden at ≤480px; requires alternative nav pattern
  • Animation: No micro-interactions added (by design, but may enhance UX)
  • Icon system: Not included; requires external icon library (minimum 24px for touch)
  • Grid system: Only flexbox utilities; CSS Grid utilities not included
  
  RESPONSIVE BREAKPOINTS ADDED:
  • ≤1024px (Tablet): Reduced sidebar, adjusted spacing, stacked headers
  • ≤768px (Mobile): Smaller typography, stacked layouts, touch-optimized forms
  • ≤480px (Small Mobile): Hidden sidebar, full-width buttons, compact cards
  • Landscape support: Special handling for mobile landscape orientation
  
  DESIGN SYSTEM VERSION: 1.2.0
  LAST UPDATED: 2026-07-09
  STATUS: Production Ready with Mobile Responsive Support

/* ============================================================
   SHARED PRIMITIVES (NEXUS-UXG-002)
   ------------------------------------------------------------
   The documented, reusable UI primitive set for the live SPA
   (lncnexus/ui/dashboard.html). New and refactored surfaces must
   use these primitives instead of page-local variants for the
   same state. Companion guide: docs/user-guide/UX-PRIMITIVES.md.

   Conventions
   - Namespace: .nx-*
   - Color is NEVER the only state signal: every state carries a
     text label and/or icon in addition to its tone.
   - Dark mode: the SPA toggles a `dark` class on <html>; every
     primitive defines an html.dark override.
   - Print: @media print rules per primitive (tone becomes a
     border, ink-saving, dialogs and toasts hidden).
   - Reduced motion: @media (prefers-reduced-motion: reduce)
     disables animation on every primitive that animates.
   - Focus: :focus-visible ring on every interactive primitive.
   - High zoom: primitives are rem-based, wrap text
     (overflow-wrap: anywhere), and stack/wrap at narrow
     effective widths (<=480px) so 200%+ zoom never clips.
