The source image had a black border baked in. Knocked out the dark pixels into an alpha channel so the figure now floats on whatever surface is behind it — the dark gradient on the splash, the panel surface on the loading indicator, anywhere.
Pipeline: source -> resize 1200w -> python/PIL alpha-from-luminance with soft 22-55 luminance ramp -> 8-bit RGBA PNG (267KB).
* Library cards now show a checkbox on hover (and persistent when selected). Click checkbox = toggle, shift-click = range. Plain click on a card with an active selection extends/shrinks the selection instead of opening preview. Floating pill at the bottom shows count + Move / Copy / Delete / Clear. Move + Copy open a tiny bin picker (current project, default to current bin).
* mam-api/routes/assets.js: PATCH /:id now also accepts bin_id (null = move out of bin). New POST /:id/copy makes a reference-copy of the asset row (same S3 keys, new id) into the target bin/project.
* api.js: moveAsset(id, binId) and copyAsset(id, {binId, projectId}) helpers.
* All accent tokens swapped from the amber oklch(76% 0.178 52) to the Wild Dragon signature blue oklch(55% 0.20 266) = #1f3ad0 ish. Login splash + first-load splash + signal-receiving + button primary all picked it up automatically through common.css.
* Loading indicator across the app uses the AMPP Safe hardhat photo gently pulsing with a tiny blue dot underneath. .ampp-loading component lives in common.css with --sm / --xs / --inline variants. Replaces the plain "Loading assets…" empty state in index.html.
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.
