Adds the BMG-branded "AMPP Safe" hardhat photo as the visual identity for the auth + first-load surfaces.
* services/web-ui/public/img/ampp-safe.jpg (52 KB, 1200w optimized JPEG)
* services/web-ui/public/login.html: full redesign as a two-column hero + sign-in panel. Hero shows the hardhat photo full-bleed with a subtle AMPP Safe pill badge and broadcast-safe caption. Login + first-run admin setup forms unchanged functionally.
* services/web-ui/public/index.html: brief first-visit splash overlay (~1.4s) using the same image. Dismisses to the library and uses sessionStorage so it only shows once per session.
Trash icon in the library was firing PATCH /assets/:id with {status:"deleted"}. The PATCH route only accepts display_name/tags/notes so it returned "No fields to update" and the asset stayed put.
* api.js: add deleteAsset(id, {hard}) helper hitting the real DELETE route.
* index.html: deleteAssetPrompt now calls deleteAsset (soft archive). Confirm dialog reworded to match.
* mam-api/routes/assets.js: list endpoint hides status=archived by default. Pass ?include_archived=true to see them in a future restore-from-trash view. Filtering by ?status=archived still works for power users.
* All HTML: bump api.js cache-buster v=4 -> v=5 so the new helper is fetched.
Click any asset card to open a modal with the H.264 proxy playing inline (or audio/image, per media_type). Esc or click outside closes. Sidebar shows status/codec/resolution/fps/duration/size/created plus tags and notes.
Plugin install side: added install-windows.ps1 that copies the CEP panel to %APPDATA%\Adobe\CEP\extensions, flips PlayerDebugMode=1 across the CSXS.8-13 hives, and prints the next steps. Plugin already wired against the current API.
* services/web-ui/public/js/preview.js: standalone IIFE that lazy-injects the modal markup + CSS on first use. Renders <video controls> (or <audio>, <img>) sourced from /api/v1/assets/:id/stream, with sidebar from /api/v1/assets/:id. Falls back to a clear empty state when proxy is still processing.
* services/web-ui/public/index.html: loads preview.js, wires asset-card click to window.openAssetPreview(asset.id), guards against delete-button clicks bubbling.
* services/premiere-plugin/install-windows.ps1: one-shot Windows installer for the CEP extension.
The api.js library-list fix from the previous commit never reached the browser because nginx served all .js with `Cache-Control: public, immutable; max-age=31536000`. The HTML referenced api.js with no version query, so the browser kept its year-cached buggy copy.
* nginx.conf: drop .js from the immutable long-cache block, add a no-cache must-revalidate block so future redeploys are picked up immediately.
* All HTML files: tag api.js refs with ?v=4 so already-running browsers fetch the new version on next page load.
