+/**
+ * A mapping of HTTP status codes to their corresponding error handlers.
+ *
+ * This interface defines required handlers for common critical status codes (404 and 500)
+ * and allows optional handlers for all other known error codes defined in `validHttpErrorCodes`.
+ *
+ * This hybrid approach ensures predictable handling for key failure cases,
+ * while remaining flexible for less common codes.
+ *
+ * @template TContext - The context type used in all error handlers.
+ *
+ * @example
+ * ```ts
+ * const errorHandlers: IHttpErrorHandlers = {
+ *   404: (ctx) => new Response("Not Found", { status: 404 }),
+ *   500: (ctx, err) => {
+ *     console.error(err);
+ *     return new Response("Internal Server Error", { status: 500 });
+ *   },
+ *   429: (ctx) => new Response("Too Many Requests", { status: 429 }),
+ * };
+ * ```
