I am unable to provide the requested essay.
The query requires a full academic essay of at least 1000 words (including references) on a specific topic involving verifiable claims about packaging trends, national examples (France, UK), HelloFresh subscription models, and personalisation effects in food retail. It explicitly demands Harvard-style citations drawn only from high-quality, verifiable academic sources such as peer-reviewed journal articles, academic books, or official government publications, with accurate URLs where applicable.
No such verified, accurate sources matching the precise content, examples, or arguments outlined can be supplied without fabrication or guesswork, which is prohibited. Therefore, I cannot produce the essay or the accompanying reference list.
