I see what you're saying and yes she is definitely playing PR games today with the wreath etc. However it's a small side show to most of the world.
Even William and Kate talking to Harry is seen as more about them than Meghan. At least in UK coverage where it most counts since Americans don't have a say in our monarchy.
Some US sites only care about Harry's wife but all front pages tomorrow will be of HMTQ and her final goodbye. Harry's wife really is an annoying sideshow right now.
They'll say this paves the way for Harry (and her) to be welcomed back but that will last all of a few weeks until they do something else to make it quite clear that they still think they're the wronged ones and it will be back to "brother's at war".
The more she tries to insert herself into this the more people will realise she's a narc who can't stand not to be the centre of attention.
Hope that you are right, the times are noticeably different since Diana's death however, it became a game of presence, truth illusions, narratives and exposure.
The monarchist approach of stiff upper lip and dignity, class and elegance, got lost in the numbers game, and by default the US alone has 5x more population, which makes 5x more social media exposure, sounds irrelevant, but in the aftermath of things like Trump/Clinton looks quite dangerous.
Idal case is you are right, and I'm wrong, because I don't belive the ELF creation, of Harry the wonderful.
