- Closed vault drawer now negates its 440px via margin-right so it reserves no layout space — the list pane and its empty state center in the full post-sidebar width instead of being shifted left by the off-screen drawer. - .vault-lock-screen gets flex:1 so the locked vault tab grows to full viewport width instead of collapsing to content width and pinning to the left.
