Invitations go stale in the wild
Once an invitation link is circulating, copies of it scatter: pinned in the family group, forwarded to a work chat, screenshotted by a friend who was being helpful. Then something changes. The ceremony moves an hour later, the marquee gets a different field, and the pinned message โ frozen, confident, wrong โ is now the problem.
An invitation page is not a printed card, and the honest way to run one is to accept that it will change after sending. The link stays the fixed object; the page behind it is allowed to move. When the venue swaps, one reply updates everything the link points at, and the stale screenshot quietly loses.
