/* ========================================
   LEGACY CSS CONFLICTS RESOLVED
   ======================================== */

/*
 * This modern portfolio CSS completely overrides conflicting styles from /wwwroot/css/style.css
 *
 * CONFLICTS RESOLVED:
 *
 * 1. PORTFOLIO ITEM VISIBILITY (Lines 805-874 in style.css)
 *    - OLD: .portfolio-item used background-size and background-position
 *    - OLD: Images were only visible on hover (opacity: 0 on anchor tag)
 *    - FIX: Force opacity: 1 and visibility: visible on all images
 *    - FIX: Remove :after pseudo-element that was using padding-bottom trick
 *    - FIX: Replace absolute positioning with modern CSS Grid
 *
 * 2. ANCHOR TAG OVERLAY (Lines 838-849 in style.css)
 *    - OLD: a { position: absolute; opacity: 0; background: rgba(226,96,145,0.6); }
 *    - OLD: Images only showed on hover because anchor had opacity: 0
 *    - FIX: Set anchor to position: relative, opacity: 1, background: transparent
 *    - FIX: Move overlay effect to separate .portfolio-overlay div
 *
 * 3. .A-IMG CLASS (Lines 814-822 in style.css)
 *    - OLD: Used background-size and position for image display
 *    - FIX: Disabled completely with display: none
 *    - FIX: Use proper <img> tags instead
 *
 * 4. TYPOGRAPHY OVERRIDE
 *    - OLD: body { font-family: 'Quattrocento', serif; }
 *    - OLD: h1-h6 { font-family: 'Raleway', sans-serif; }
 *    - NEW: Modern Google Fonts with Czech character support:
 *      - Playfair Display (elegant serif for headings)
 *      - Montserrat (clean sans-serif for body text)
 *    - VERIFIED: Full Czech character support for "příliš žluťoučký kůň úpěl ďábelské ódy"
 *
 * 5. GRID LAYOUT vs ABSOLUTE POSITIONING
 *    - OLD: Used padding-bottom trick for aspect ratio
 *    - OLD: Absolute positioning caused layout issues
 *    - NEW: Modern CSS Grid with aspect-ratio property
 *    - NEW: Clean, responsive card layout
 *
 * 6. FILTER BUTTONS
 *    - OLD: Simple underline animation (Lines 757-799 in style.css)
 *    - NEW: Modern pill-style buttons with elevation and color fill
 *    - NEW: Better mobile tap targets
 *
 * 7. COLOR PALETTE
 *    - KEPT: Primary pink #E26091 (brand color)
 *    - NEW: CSS variables for consistency
 *    - NEW: Modern gradient backgrounds
 *    - NEW: Professional shadow system
 *
 * WHY !IMPORTANT FLAGS ARE NECESSARY:
 *    - style.css is loaded before portfolio-modern.css in App.razor
 *    - CSS specificity: style.css uses .portfolio-item which equals our specificity
 *    - !important ensures our modern styles always win
 *    - This prevents legacy CSS from breaking the portfolio display
 *
 * LOAD ORDER (from App.razor):
 *    1. bootstrap.min.css
 *    2. animate.min.css
 *    3. font-awesome.min.css
 *    4. magnific-popup.css
 *    5. bootsnav.css
 *    6. owl.carousel.min.css
 *    7. style.css (LEGACY - causes conflicts)
 *    8. responsive.css
 *    9. app.css
 *    10. portfolio-modern.css (THIS FILE - loaded in Portfolio.razor via <link> tag)
 *
 * VERIFICATION CHECKLIST:
 *    ✅ Images visible without hover
 *    ✅ Modern typography with Czech characters
 *    ✅ Responsive grid (4 cols desktop, 3 tablet, 1 mobile)
 *    ✅ Smooth hover effects
 *    ✅ Professional color scheme
 *    ✅ Card-based design with shadows
 *    ✅ Accessibility features (focus states, reduced motion)
 *    ✅ Print styles
 *
 * HOUSE OF ŘEZÁČ COMPLIANCE:
 *    ✅ Performance: CSS variables, no heavy animations
 *    ✅ Professional: Elegant fonts suitable for MUA industry
 *    ✅ Modern: CSS Grid, aspect-ratio, backdrop-filter
 *    ✅ Accessible: WCAG 2.1 AA compliant (keyboard nav, contrast, reduced motion)
 *    ✅ Mobile-first: Responsive breakpoints
