A control readout beside the launch pad: tower, rocket and astronaut in a column of their own, sticker rows, the age as the mission patch, and the code out on the apron.
The paper already in your printer. This is the ink-saving version: white paper, the party's accent kept and nudged until it stays legible on it. Switch back to Full colour for the version that looks like the party.
The code goes to the invitation site itself, so a guest who scans it lands on the countdown, the address and the RSVP — not on an app store.
The name Ava is invented, and so is the party — the QR on this sheet opens the matching sample invitation. Yours carries your child’s name and links to your own invite.
