-// NegotiateAccept takes the *gin.Context from an incoming request, and a
-// slice of Offers, and performs content negotiation for the given request
-// with the given content-type offers. It will return a string representation
-// of the first suitable content-type, or an error if something goes wrong or
-// a suitable content-type cannot be matched.
-//
-// For example, if the request in the *gin.Context has Accept headers of value
-// [application/json, text/html], and the provided offers are of value
-// [application/json, application/xml], then the returned string will be
-// 'application/json', which indicates the content-type that should be returned.
-//
-// If the length of offers is 0, then an error will be returned, so this function
-// should only be called in places where format negotiation is actually needed.
-//
-// If there are no Accept headers in the request, then the first offer will be returned,
-// under the assumption that it's better to serve *something* than error out completely.
-//
-// Callers can use the offer slices exported in this package as shortcuts for
-// often-used Accept types.
