   UI BLUEPRINT
   ============================================

   TYPOGRAPHY SCALE (Mobile-first):
   - H1 (district title): 28px / 1.2 / 700 (mobile), 36px (desktop)
   - H2 (section title): 24px / 1.3 / 600 (mobile), 28px (desktop)
   - H3 (card title): 18px / 1.4 / 600 (mobile), 20px (desktop)
   - Body (meta, count): 14px / 1.5 / 400
   - Price: 20px / 1.2 / 700 (mobile), 22px (desktop)
   - Small (meta text): 13px / 1.5 / 400

   SPACING SYSTEM:
   - Section gap: 32px (mobile), 48px (tablet), 64px (desktop)
   - Grid gap: 16px (mobile), 24px (tablet), 32px (desktop)
   - Card padding: 0 (image + content separation)
   - Card content padding: 12px (mobile), 16px (desktop)
   - Toolbar gap: 16px (mobile), 24px (desktop)
   - Internal spacing (meta, price): 8px vertical

   CARD ANATOMY:
   - Image ratio: 16:10 (1.6) - prevents CLS
   - Image: Full width, object-fit cover, border-radius 12px top
   - Title: 2-line clamp (line-height 1.4, max-height ~56px)
   - Meta: Horizontal flex, bullet separator, muted color
   - Price: Bottom-aligned, bold, primary color
   - Border radius: 12px (card), 10px (image top)
   - Shadow: 0 1px 3px rgba(0,0,0,0.12), 0 1px 2px rgba(0,0,0,0.24) (subtle elevation)
   - Hover: transform translateY(-2px), shadow elevation

   RESPONSIVE BREAKPOINTS (Mobile-first):
   - Mobile: < 768px (1 column grid)
   - Tablet: 768px - 1023px (2 column grid)
   - Desktop: >= 1024px (3 column grid)
   - Large: >= 1200px (3 column, larger gaps)

   A11Y CONSIDERATIONS:
   - Touch targets: Minimum 44x44px (buttons, pagination)
   - Focus styles: 2px solid outline, offset 2px
   - Color contrast: WCAG AA (4.5:1 for normal text)
