I spent the last couple of days fixing a lot of bugs and also made some polishes here and there.

1. Page weight went from about 20 MB to around 1 MB on mobile.
2. The data payload went from 3210 KB to around 47 KB.
3. The gift links went from three KV writes to just one.
4. Fixed the date field being invisible on Android.
5. Some APOD entries are GIFs. They exported in the gift card as black rectangles. I fixed it by requesting a mid-sequence frame plus a luminance check on the export as a backstop.

Previews were broken till this phase, so I fixed them as well through routing them through a proxy at a declared 1200×630. Also, some more polishes here and there. I do think it is finally ready to ship!!!
