Add tbis to App Stories

[mahi160]

App

Add tbis, a native macOS client for Jellyfin, to App Stories. It is built with GPUI Kit and plays video through an embedded mpv. The app is in early development (version 0.0.1), so the manifest sets building: true.

• Add the manifest and four full-window PNG previews taken from the current build, connected to the public Jellyfin demo server (demo.jellyfin.org/stable) with the demo guest account.
• The previews show the Home screen (Raptor Night theme, cover), the Movies library (Stego Dusk), a movie detail page (Bronto Morning, light theme) and a series detail page with its episode list (Raptor Night).
• Each preview is a 2560 × 1600 window capture with the title bar, all four corners and all four edges intact.

Source verification

Verified against upstream commit ffe767116c5d933386b4552584b80b1fbd066477:

• Cargo.toml depends on gpui-kit = "0.6.6".
• The UI in src/ imports GPUI Kit components such as Button, TabBar, Icon and ActiveTheme (for example, src/series.rs).

publishedAt is provisionally set to 2026-10-05T06:18:49Z because the validator requires it. Maintainers should confirm the first-inclusion timestamp before merging. Featured selection and Stars metadata are untouched.

Checks

• Used a lowercase kebab-case folder and matching manifest id.
• Provided author, source, and an English description within 280 weighted characters.
• Committed preview images in the app folder; previews contains only local filenames.
• Screenshots are clear and tidy, with all four corners and all four window edges intact.
• No app README is included.
• Left Featured selection, first inclusion time, and Stars metadata to maintainers/automation.
• Ran bun test (22 pass) and bun run validate (66 app manifests validated).

Every merged app PR is listed in App Stories. Maintainers select and periodically adjust Featured placement; it is not guaranteed.
