- the Suspense fallback (shown on every cold load while the app chunk loads, longer on slow/mobile connections) was a plain monospace 'Loading amerc…' - replace with a branded screen: a pulsing cyan gem over 'amerc' in gold Georgia on a dark radial background, matching the logo + error-boundary look - respects prefers-reduced-motion - also audited the public mobile surfaces (agent modal, status, changelog) — all mobile-safe (modal is width:min(640px,96vw) + scroll) - verified the loading screen renders (blocked the app chunk to capture it)
