+
+This file provides guidance for AI coding agents working in this repository.
+
+## Project Overview
+
+Top 500 Albums analysis with data from Rolling Stone (2020) and Wikipedia (2023). Includes Python data processing scripts, an interactive web interface (vanilla HTML/CSS/JS), and album cover artwork from the iTunes API.
+
+## Build/Lint/Test Commands
+
+**No formal build system.** All Python scripts use only the standard library.
+
+```bash
+# Run Python scripts directly
+python scripts/download_all_covers.py
+python scripts/compare_top500_albums.py
+
+# Local dev server (required for CORS)
+python -m http.server 8000
+```
+
+**No tests or linting configured.** Manual testing only - run scripts and verify output, open website and check functionality.
+
+## Code Style Guidelines
+
+### Python
+
+```python
+#!/usr/bin/env python3
+"""Module docstring explaining the script's purpose."""
+
+import csv
+import json
+import os
+import re
+from typing import Dict, List, Optional, Tuple
+
+# Constants: UPPER_SNAKE_CASE
+MAX_RETRIES = 3
+
+# Functions/variables: snake_case
+def normalize_text(text: str) -> str:
+    """Normalize text for comparison."""
+    pass
+
+albums_2020 = {}
+```
+
+**Key patterns:**
+- Always use shebang: `#!/usr/bin/env python3`
+- Include module-level docstring
+- Standard library only - no external dependencies
+- Type hints for function signatures
+- Use `encoding='utf-8'` and `newline=''` for CSV operations
+
+**Error handling:**
+```python
+try:
+    with urllib.request.urlopen(url, timeout=15) as response:
+        data = json.loads(response.read().decode())
+except Exception as e:
+    print(f"Error: {e}")
+    return None
+```
+
+### JavaScript
+
+```javascript
+// Global variables at top
+let albumsData = [];
+const itemsPerPage = 50;
+
+// DOM refs cached on load
+const albumsGrid = document.getElementById('albumsGrid');
+
+// Initialize on DOMContentLoaded
+document.addEventListener('DOMContentLoaded', function() {
+    loadData();
+});
+
+// Async/await for fetch
+async function loadAlbumsData() {
+    try {
+        const response = await fetch('data.csv');
+        if (!response.ok) throw new Error('Failed');
+        // ...
+    } catch (err) {
+        console.error('Error:', err);
+    }
+}
+```
+
+**Key patterns:**
+- Variables/functions: camelCase
+- Use `console.warn()` for non-critical failures
+- Vanilla JS only - no frameworks
+
+### HTML/CSS
+
+- Semantic HTML5 elements
+- CSS custom properties for theming
+- Responsive design with Grid/Flexbox
+
+## Accessibility Requirements
+
+All UI changes must follow WCAG 2.1 AA guidelines:
+
+**Keyboard Navigation:**
+- All interactive elements must be keyboard accessible
+- Use `tabindex` appropriately (0 for focusable, -1 for programmatic focus)
+- Implement visible focus indicators (`:focus-visible` with `outline`)
+- Support skip links for main content
+
+**Screen Readers:**
+- Use semantic HTML (`<button>`, `<nav>`, `<main>`, `<article>`)
+- Add ARIA labels for icon-only buttons: `aria-label="Share album"`
+- Use `.sr-only` class for screen-reader-only text
+- Ensure proper heading hierarchy (`h1` > `h2` > `h3`)
+
+**Color & Contrast:**
+- Minimum 4.5:1 contrast ratio for normal text
+- Minimum 3:1 for large text and UI components
+- Never use color alone to convey information
+
+**Motion & Animations:**
+- Respect `prefers-reduced-motion` media query
+- Avoid layout shifts on hover (no `transform: translateY()` on cards)
+
+**Focus Management:**
+- Trap focus in modals/dialogs
+- Return focus to trigger element when closing overlays
+
+**Existing Patterns:**
+```css
+/* Screen reader only */
+.sr-only { position: absolute; width: 1px; height: 1px; ... }
+
+/* Focus indicators */
+button:focus-visible { outline: 2px solid var(--primary-color); outline-offset: 2px; }
+
+/* Reduced motion */
+@media (prefers-reduced-motion: reduce) { ... }
+```
+
+## Project Structure
+
+```
+top500albums/
+├── index.html, script.js, styles.css  # Website
+├── *.csv, *.json                       # Data files
+├── covers/                             # Album artwork (500 images)
+└── scripts/                            # Python utilities (36 scripts)
+```
+
+## Data Files
+
+| File | Notes |
+|------|-------|
+| `rolling_stone_top_500_albums_2020.csv` | Title case columns, ranks in reverse order |
+| `wikipedia_top_500_albums.csv` | Lowercase columns (`rank`, `artist`, `album`) |
+| `top_500_albums_2023.csv` | Combined comparison file |
+
+## Key Patterns
+
+**CSV column naming:**
+- Rolling Stone/Combined: Title case (`Rank`, `Artist`, `Album`)
+- Wikipedia: lowercase (`rank`, `artist`, `album`)
+
+**Album matching:** Uses `difflib` for fuzzy matching variations like "The Beatles" vs "Beatles"
+
+**API rate limiting:** `time.sleep(1.2)` between requests
+
+## Common Tasks
+
+**New Python script:**
+1. Create in `scripts/`, add shebang + docstring
+2. Standard library only
+3. Include `if __name__ == "__main__":` block
+
+**Working with album data:**
+```python
+import csv
+with open('top_500_albums_2023.csv', 'r', encoding='utf-8') as f:
+    for row in csv.DictReader(f):
+        rank, artist, album = int(row['Rank']), row['Artist'], row['Album']
+        status = row['Status']  # "New in 2023", "+10", "-5", "No change"
+```
