fix: describe the share card that exists, not a different one

The og:image:alt on the home page said the card shows the desktop app reading
two files and stopping to ask permission. It does not — the card is a crop of
the hero: the chrome wordmark over the headline. I wrote the alt from the image
I had meant to use rather than from the one I generated.

Alt text that describes a different picture is worse than none: a screen reader
announces a scene that is not there, and nothing in the page contradicts it.
