Base .empty-state now flex-centers its icon/title/hint/CTA with a
140px min-height so icon-bearing empty states in the Dashboard side
panels (DECKIES UNDER SIEGE, TOP ATTACKERS) stop looking cramped.
Component-scoped rules (attackers-root, bounty-root, logs-root)
remain more specific and are unaffected.
- Modal: shared backdrop/panel with ESC-close, backdrop-click-close,
focus trap, body scroll lock; supports center + drawer-right variants,
matrix/violet accents, default/wide widths.
- EmptyState: icon + title + hint + optional CTA; compact variant
for tight rails.
- useEscapeKey, useFocusTrap: reusable hooks powering Modal; will also
be adopted by CommandPalette and ContextMenu in follow-up commits.
No retrofits yet — primitives only. tsc clean.
