+// Package laniakea provides a modular, extensible framework for building scalable
+// Telegram bots with support for plugins, middleware, localization, draft messages,
+// rate limiting, structured logging, and dependency injection.
+//
+// The framework is designed around a fluent API for configuration and separation of concerns:
+//
+//   - Plugins: Handle specific commands or events (e.g., /start, /help)
+//   - Middleware: Intercept and modify updates before plugins run (auth, logging, validation)
+//   - Runners: Background goroutines for cleanup, cron jobs, or monitoring
+//   - DraftProvider: Safely build and resume multi-step messages
+//   - L10n: Multi-language support via key-based translation
+//   - RateLimiter: Enforces Telegram API limits to avoid bans
+//   - Structured Logging: JSON stdout + optional file output with request-level tracing
+//   - Dependency Injection: Inject custom database contexts (e.g., *gorm.DB, *sql.DB)
+//
+// Example usage:
+//
+//	bot := laniakea.NewBot[mydb.DBContext](laniakea.LoadOptsFromEnv()).
+//		DatabaseContext(&myDB).
+//		AddUpdateType(tgapi.UpdateTypeMessage).
+//		AddPrefixes("/", "!").
+//		AddPlugins(&startPlugin, &helpPlugin).
+//		AddMiddleware(&authMiddleware, &logMiddleware).
+//		AddRunner(&cleanupRunner).
+//		AddL10n(l10n.New())
+//
+//	go bot.Run()
+//	<-ctx.Done() // wait for shutdown signal
+//
+// All methods are thread-safe except direct field access. Use provided accessors
+// (e.g., GetDBContext, SetUpdateOffset) for safe concurrent access.

+// Package laniakea provides a high-level context-based API for handling Telegram
+// bot interactions, including message responses, callback queries, inline keyboards,
+// localization, and message drafting. It wraps tgapi and adds convenience methods
+// with built-in rate limiting, error handling, and i18n support.
+//
+// The core type is MsgContext, which encapsulates the state of a Telegram update
+// and provides methods to respond, edit, delete, and translate messages.
+//
+// # Markdown Safety Warning
+//
+// All methods that accept MarkdownV2 formatting (e.g., AnswerMarkdown, EditCallbackfMarkdown)
+// require that user-provided text be escaped using laniakea.EscapeMarkdownV2().
+// Failure to escape user input may result in Telegram API errors, malformed messages,
+// or security issues.
+//
+// Example:
+//
+//	text := laniakea.EscapeMarkdownV2(userInput)
+//	ctx.AnswerMarkdown("You said: " + text)
