1a1A shared link that previews as a grey box does not get opened
The entire distribution model is someone pasting the link into a chat. A client-rendered 3D app gives crawlers an empty shell, so the preview is blank and the link looks like spam.

1 · Overview
What it is, and why it exists.
Pick a gift, record a voice note, send a link. The recipient opens a 3D scene that unwraps in the browser. Free, no accounts, and the sender gets an email when it is opened.
A greeting sent as a link is usually a static page with a name interpolated into it. This one is a real 3D scene: the gift sits there wrapped, and opening it is an animation rather than a page load.
Senders can attach a voice note, and get an email when the gift is actually opened, which turns out to be the part people care about most.
1a · Challenges
Each problem got a card. Each fix got filed behind it.
1a1aWhat I did
Crawlers hitting a gift URL are rewritten to a server function that returns per-gift Open Graph tags, while real visitors get the full 3D app. The preview is correct without server-rendering a WebGL scene.
1a23D scenes and server rendering do not mix
React Three Fiber needs a canvas and a browser; server rendering it produces hydration mismatches and a flash of broken layout before the scene appears.
1a2aWhat I did
The app tree renders client-only behind a mounted gate, so it behaves like a single-page app while the routes around it stay server-rendered. Fighting the framework here would have cost more than accepting the boundary.
2 · Results
- Per-gift link previews without server-rendering WebGL.
- Voice notes and open-notification emails, with no account required.
