+- **The admin pages fit a phone.** At 390 px, Activity, Clients, Diagnostics and every configuration table scrolled sideways, and Diagnostics and Clients made the whole page 826 px and 660 px wide, so the phone zoomed out. A table now shows all its columns only where they fit without wrapping. In a narrower table, the first cell carries the other columns' facts on short lines ("Priority 20 · TLS name dns.quad9.net", "Created 19 Oct 2026, 16:15:44"), and long names, URLs, IPv6 addresses and patterns wrap instead of widening the page. In the narrow Sources and Upstreams tables, Edit and Delete stack, which gives the first cell the width. Protection > Sources needs a 1440 px wide table for all its columns, so a 1440 px window now shows its narrow form; in 0.0.23 it made the page 1557 px wide there.
+- **Overview is no longer taller than the window.** The charts' screen-reader tables extended the document below the app, so the page had a second scroll bar under the main one at desktop widths.
+- **The Diagnostics count line no longer spreads its words across the page.**
+- **The Diagnostics health cards no longer spread a short card's lines down its height.**
