setup.html was the only page not using the .app-shell CSS grid — its
elements were directly on the body with inline position styles. Wraps
content in .app-shell--live (viewport-filling variant), moves header
into .app-header grid area, and nests #scene-container inside .app-main.
Verified: grep for position:absolute across dashboard/css/ returns only
intentional decorative/component uses (pseudo-elements, toggles, tooltips,
dropdowns, canvas overlays) — zero on layout containers.

The home page (index.html) was restructured into status headline + 3 cards.
The 3D viewer lives at /live (live.html), setup/calibration at /setup (setup.html).
Fleet page remains at /fleet. home-cards.js pulls snapshot from /ws/dashboard.
