The invitations, and the quiet machinery
Graduation invitations usually start as a poster in the family chat, which is fine for one hour and then becomes archaeology: details scroll away, and the replies come in fragments across three threads. Build instead a single page the graduate's name sits on top of — ceremony and party both on the same link — and send that link everywhere once.
The page quietly does the counting. Each yes attaches to a name, meal notes arrive with the reply for whoever is cooking, and the ones who say nothing can be reminded from the list rather than hunted through chats. After the party, wishes and photographs gather on the same page, which makes a better gift to the graduate than any decoration did: a record of who came and what the afternoon looked like.
