- Mobile / phone-friendly layout. The whole app is now usable from a phone in the field. The sidebar becomes a slide-in drawer behind a hamburger menu, tables either reflow into stacked cards or scroll sideways instead of clipping, modals open as full-width bottom sheets, the log viewer stacks each entry so messages are actually readable, and tap targets and form fields are sized for touch. The desktop layout is unchanged.
- Topology is desktop-only. The interactive map needs a larger screen, so on a phone it's hidden from the menu and shows a short "Not available on mobile" notice if opened directly.
