Claude f1a3d6a24a fix(premiere-plugin-uxp): v2.0.1 — replace unsupported CSS + surface load count 
The v2.0.0 grid stayed empty in Premiere 26 because UXP's CSS engine
doesn't support `grid-template-columns: repeat(auto-fill, minmax(...))`
or `aspect-ratio`. Cards rendered with 0 height and the flex column
collapsed, so the actions row stuck to the top of the pane.

Switch to flex-wrap with fixed-width (140px) cards and explicit 80px
thumb heights — both work in UXP's stripped CSS.

Also fix the /auth/me response shape — it returns the user fields
directly, not wrapped in `{ user: ... }`. Header now shows
"display_name @ host" instead of falling back to bare host.

Add a toast on each library load reporting "Loaded N assets (total M)"
so we can tell empty-grid (zero assets) from CSS-broken-grid (cards
exist but invisible) at a glance.

Dragonflight MAM — Premiere Pro UXP panel (v2.0.0)

The successor to the CEP panel at services/premiere-plugin/.

Why this exists: Premiere Pro 26.0.x broke csInterface.evalScript's return-value callback — it no longer fires. That deadlocks any CEP panel that needs to call back into Premiere (importFiles, sequence access, etc). Adobe's path forward is UXP; this panel is the minimum viable port that restores the Import Proxy / Import Hi-Res workflow.

Scope (v2.0.0)

In:

  • Connect to a Dragonflight server (URL + Bearer token, persisted in localStorage)
  • Browse the asset library (search, refresh, grid with thumbnails)
  • Import Proxy — downloads the proxy MP4 and adds it to the active project
  • Import Hi-Res — downloads the original from S3 (presigned URL) and imports

Out (carried over from the CEP panel later, as v2.x):

  • Mount Live (SMB live preview)
  • Conform / Auto-Relink / Batch Trim
  • Timeline export
  • Settings tabs (Account, Tokens, S3) — use the web UI for now

Build

Requires Node 18+.

cd services/premiere-plugin-uxp
node build/pack.mjs
# → build/dist/dragonflight-mam-2.0.0.ccx

(Uses system zip. On Windows hosts use Compress-Archive — error message shows the exact command.)

Install on Windows

Prerequisite: Premiere Pro Preferences > Plugins > Enable developer mode must be toggled on (one-time, per machine). This is required for any UXP plugin not distributed via Creative Cloud Marketplace.

& "C:\Program Files\Common Files\Adobe\Adobe Desktop Common\RemoteComponents\UPI\UnifiedPluginInstallerAgent\UnifiedPluginInstallerAgent.exe" /install "C:\path\to\dragonflight-mam-2.0.0.ccx"

That writes to %APPDATA%\Adobe\UXP\Plugins\External\net.wilddragon.dragonflight.uxp\ and registers the plugin with UPIA.

To uninstall:

& "...\UnifiedPluginInstallerAgent.exe" /remove net.wilddragon.dragonflight.uxp

Open the panel in Premiere via Window > Extensions > Dragonflight MAM.

Development loop (Adobe UXP Developer Tool)

For iterative dev without rebuilding+reinstalling:

  1. Install Adobe UXP Developer Tool ("UDT") from Creative Cloud.
  2. UDT → Add Plugin → point at this folder.
  3. Load → opens the panel in Premiere with hot-reload.

Known limits

  • Adobe strips Authorization headers on cross-origin redirects. import-flow.js uses redirect: 'manual' and drops the Bearer when hopping to a different host (e.g. when the server 302s us to the S3 endpoint).
  • Project.importFiles() returns a boolean, not the new ProjectItem. To locate the imported item, Import.locateImported(project, filename) does a rootItem.getItems() diff after import.
  • UXP's os.tmpdir() resolves to Windows %TEMP% which is cleared by Disk Cleanup. For long-lived downloads, persist explicitly elsewhere.
