+// Package tmdb provides a client for The Movie Database (TMDB) API.
+//
+// This package offers a clean interface for interacting with TMDB's REST API,
+// including automatic rate limiting, retry logic, and convenient URL building utilities.
+//
+// # Getting Started
+//
+// First, create an API connection using your TMDB API token:
+//
+//	api, err := tmdb.NewAPIConnection()
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+// The token is read from the TMDB_TOKEN environment variable.
+//
+// # Making Requests
+//
+// The package provides clean URL building functions to construct API requests:
+//
+//	// Simple endpoint
+//	url := tmdb.requestURL("movie", "550")
+//	// Result: "https://api.themoviedb.org/3/movie/550"
+//
+//	// With query parameters
+//	url := tmdb.buildURL([]string{"search", "movie"}, map[string]string{
+//		"query": "Inception",
+//		"page":  "1",
+//	})
+//	// Result: "https://api.themoviedb.org/3/search/movie?language=en-US&page=1&query=Inception"
+//
+// All requests made with buildURL automatically include "language=en-US" by default.
+//
+// # Rate Limiting
+//
+// TMDB has rate limits around 40 requests per second. This package implements
+// automatic retry logic with exponential backoff:
+//
+//   - Initial backoff: 1 second
+//   - Exponential growth: 1s → 2s → 4s → 8s → 16s → 32s (max)
+//   - Maximum retries: 3 attempts
+//   - Respects Retry-After header when provided by the API
+//
+// Example of rate-limited request:
+//
+//	data, err := api.get(url)
+//	if err != nil {
+//		// Will return error only after exhausting all retries
+//		log.Printf("Request failed: %v", err)
+//	}
+//
+// # Searching for Movies
+//
+// Search for movies by title:
+//
+//	results, err := tmdb.SearchMovies(token, "Fight Club", false, 1)
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	for _, movie := range results.Results {
+//		fmt.Printf("%s %s\n", movie.Title, movie.ReleaseYear())
+//		fmt.Printf("Poster: %s\n", movie.GetPoster(&api.Image, "w500"))
+//	}
+//
+// # Getting Movie Details
+//
+// Fetch detailed information about a specific movie:
+//
+//	movie, err := tmdb.GetMovie(550, token)
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	fmt.Printf("Title: %s\n", movie.Title)
+//	fmt.Printf("Overview: %s\n", movie.Overview)
+//	fmt.Printf("Release Date: %s\n", movie.ReleaseDate)
+//	fmt.Printf("IMDb ID: %s\n", movie.IMDbID)
+//
+// # Getting Credits
+//
+// Retrieve cast and crew information:
+//
+//	credits, err := tmdb.GetCredits(550, token)
+//	if err != nil {
+//		log.Fatal(err)
+//	}
+//
+//	fmt.Println("Cast:")
+//	for _, actor := range credits.Cast {
+//		fmt.Printf("  %s as %s\n", actor.Name, actor.Character)
+//	}
+//
+//	fmt.Println("\nCrew:")
+//	for _, member := range credits.Crew {
+//		if member.Job == "Director" {
+//			fmt.Printf("  Director: %s\n", member.Name)
+//		}
+//	}
+//
+// # Image URLs
+//
+// The API configuration includes base URLs for images. Use helper methods to
+// construct full image URLs:
+//
+//	posterURL := movie.GetPoster(&api.Image, "w500")
+//	// Available sizes: "w92", "w154", "w185", "w342", "w500", "w780", "original"
+//
+// # Error Handling
+//
+// The package returns wrapped errors for easy debugging:
+//
+//	data, err := api.get(url)
+//	if err != nil {
+//		if strings.Contains(err.Error(), "rate limit exceeded") {
+//			// Handle rate limiting
+//		} else if strings.Contains(err.Error(), "unexpected status code") {
+//			// Handle HTTP errors
+//		} else {
+//			// Handle network errors
+//		}
+//	}
+//
+// Common error scenarios:
+//   - "rate limit exceeded: maximum retries reached" - All retry attempts exhausted
+//   - "unexpected status code: 401" - Invalid API token
+//   - "unexpected status code: 404" - Resource not found
+//   - Network errors for connectivity issues
+//
+// # Environment Variables
+//
+// The package uses the following environment variable:
+//
+//   - TMDB_TOKEN: Your TMDB API access token (required)
+//
+// Obtain an API token from: https://www.themoviedb.org/settings/api
+//
+// # Best Practices
+//
+// 1. Reuse the API connection instead of creating new ones for each request
+// 2. Use buildURL for consistency and automatic language parameter injection
+// 3. Handle rate limit errors gracefully - they indicate temporary service issues
+// 4. Cache API responses when appropriate to reduce API calls
+// 5. Use specific image sizes instead of "original" to save bandwidth
+//
+// # API Documentation
+//
+// For complete TMDB API documentation, visit:
+// https://developer.themoviedb.org/docs
+//
+// # Rate Limiting Details
+//
+// From TMDB's documentation:
+// "While our legacy rate limits have been disabled for some time, we do still
+// have some upper limits to help mitigate needlessly high bulk scraping. They
+// sit somewhere in the 40 requests per second range."
+//
+// This package automatically handles rate limiting with exponential backoff to
+// ensure respectful API usage.
