How to try this invitation
Three things to do with one sample invitation. It is a design study: the couple, the date, the venue and the number do not exist.
Open the envelope
Open the invitation turns the flap back and slides the card out, then moves to the card’s title. The card is always in the page below the envelope; scroll to it at any time. With reduced motion, or without JavaScript, the envelope is already open.
Address it to a guest
Add ?untuk= and a name to the address. Up to 60 letters, digits, spaces and . , ' - ( ) are shown on the envelope and offered to the reply card; anything else shows the general greeting. The name is only read from the link: it is not stored and not sent.
Reply
Fill in the reply card: your name, attendance, guests and events when attending, and wishes. Send with WhatsApp opens a wa.me link with the same text as the preview and Copy message, to the sample number.
Two guest links to try
?untuk=Mrs Sari (sample)· a name, shown on the envelope?untuk=<b>Budi</b>· refused: the general greeting
What is kept, and how to clear it
One reply draft in this browser’s storage under collection-sampul-rsvp-v1 (at most 2 KiB): name, attendance, guests, events and wishes. It is written only after you change the form; a name from the link is kept only once you edit the name field. No cookie, account, guest list or server; nothing is sent.
Delete draft asks first, then removes it; a message you already copied or sent stays where it is. If the browser blocks or fills its storage, the form still works on the page and says it will be lost when the page closes; if what is stored cannot be read, the form starts empty and says so.
Where the sample stops
+44 7700 900142 is from a range reserved for drama and belongs to no one; every message ends “(Sample message from Sampul, a fictional invitation.)”. The plan is schematic, not a map, and the map link appears only when the content gives one. The calendar file and the countdown use the sample date in WIB.
Before real use the couple’s names, parents, date, venue, address, map link, WhatsApp number and the closing line must all be replaced. Music, verses or prayers, gift accounts or QRIS, photographs and a public guest book are outside this study.
