Replaces the generic round-shield-with-thin-check mark with a logo that
matches the actual brand palette:
- Shield body uses the vulncheck-blue (#0066FF) primary token with a
subtle vertical gradient to deeper royal blue. Reads well on the
bg-gray-900 sidebar and the bg-gray-50 login screen alike.
- Bold white check (44pt stroke) with a soft inner highlight — no toy /
crosshair vibe.
- Small securis-success (#10B981) ping at the check terminus = the
"vulnerability verified / cleared" semantic.
- Stays crisp at 24px (favicon, browser tab) up to 240px (login).
No code changes required — all consumers (layout.tsx favicon, login
page, AppShell, Drawer) already point at /logo.svg.
