CaseWrap Studio is a static print-layout editor for physical media packaging. It supports DVD/Blu-ray case wraps, Avery 8960/8944 disc-label sheets, Avery 8693/8943 CD jewel-case insert sheets, and reusable single-disc designs.

What it supports

Separate front, spine, and back case artwork (or one combined wrap image)
Disc-label sheet mode (two print positions on one Avery 8960/8944 sheet)
CD jewel insert mode (front + tray inserts on one Avery 8693/8943 sheet)
Disc Designer mode for creating a reusable single-disc design
Additional image and text layers
Drag positioning, z-order changes, rotation, sizing, and opacity
PDF export through the browser print dialog
Nostr community browsing/sharing for templates and disc designs
Publishing, replies, reactions, follows, and reposts from inside the app

Important workflow

All image sources are remote URLs.

That means:

Case art, disc art, jewel insert art, and extra image layers should use http or https URLs
Saved project JSON remains portable across machines
Exported/copied Nostr events can reconstruct layouts from event content
Community feed data comes from relays listed in the Community panel
Publishing/social actions require a NIP-07 browser extension (for example Alby or nos2x)

If a URL stops working later, the image will no longer render. For long-term reliability, use stable hosted URLs.

Main file

src/index.html is the complete app entrypoint. Open it directly in a browser or serve it from any static host.

Export and print

Use Print / Save PDF for print-ready output
Keep browser scale at 100%
Disable browser headers and footers

Save project writes project JSON
Load project restores project JSON
Copy Nostr event copies a signed event payload
Import from Nostr restores a template/design from a copied event
The Community modal lets you browse New/Popular/Search/Mine, preview templates, and import them
Disc designs can be published and reused independently, then imported into Disc 1 or Disc 2 positions on a disc sheet

Nostr data model

Template/design payloads are published as kind 30078 app-data events with casewrap tags
Typical social events use standard kinds (1, 7, 6, 3, 0)
Template modes include cover, disc, jewel, and disc-design
Current schema version is 5; minimum supported schema version is 4

Notes

The app is fully static and does not require a backend
Local browser autosave is still available
Older saved projects with embedded data URLs may still load, but new work should use remote URLs
