- Single .host-row CSS rule replaces 13 inline grid-template-columns copies; column widths bumped so "backup running…" doesn't wrap. - Faint left-edge accent for degraded / failed / offline rows so problem hosts are scannable without reading. - Empty-state hero added: top-bar + nav still present (Dashboard active, others dimmed) but body collapses to a calm "no hosts yet" prompt with the install command as the load-bearing affordance. Prerequisite note keeps the deliberate "restic must already be installed" decision visible to first-time operators. This is the artefact P1-23/24/27 will template against.
