Ethernet details in the panel, smaller maps, no tray in workspace peeks

- control.rs: Menu::Ethernet; the panel morphs into the card's details
  (gathered off the drawing thread first) instead of a separate popup;
  prompt::copy now takes a callback so both use wl-copy the same way
- prompt.rs: the Details popup is gone
- map.rs: 920x460, at most 8 nodes, lighter nearness pull (simulated:
  no label overlaps up to 8 nodes while drifting)
- workspaces.rs: a peek on a workspace change shows the workspaces alone

 - **System tray:** right of the workspace pill, a pill with every tray app's icon (StatusNotifierItem). Left click activates the app (or opens its menu if that's all it offers), right click opens its menu, drawn in the island's look (checkmarks, separators, submenus with a way back, disabled entries dim), middle click is the app's secondary action, scrolling its scroll. Nothing on this desktop ran a tray watcher, so the shell owns `org.kde.StatusNotifierWatcher` on the session bus and serves it (if another bar already does, the shell shows no tray). Icons come from the app's icon name (its own theme folder, gtk's icon theme, hicolor, AdwaitaLegacy, Adwaita, `/usr/share/pixmaps`) or from the pixels it sends, written as PNGs to `$XDG_RUNTIME_DIR/amane-tray/`. An app that quits takes its icon with it (`src/tray.rs`).
 - **Control centre:** top right on every monitor, a pill with Ethernet, Wi-Fi (or the hotspot), VPN, Bluetooth and the battery. Click it and it opens, in the island's way, into a panel like macOS's Control Center. See [Control centre](#control-centre).
 - **Out of the way of fullscreen windows:** on a monitor whose workspace shows a fullscreen window (Hyprland fullscreen 2 or 3; only maximised keeps the bar), the island, the workspace pill (with the tray) and the control centre's pill slide out of sight. Resting the pointer on that monitor's top edge for 0.3 s brings them back until it has been off them and the edge for 0.7 s; an open card or panel stays. Everywhere else the bar is always there. Hyprland's event socket says when windows go fullscreen or workspaces change, and its command socket answers `monitors` and `clients`; nothing polls. The edge strip is a one-pixel Overlay layer, there only on fullscreen monitors (it takes their top pixel row). While hidden the bar draws nothing at all, a playing player included (`src/edge.rs`).
-- **Peeks:** some events bring one part in for a moment over a fullscreen window: the workspace pill for 1.6 s when the workspace changes (with the disc sliding over), the island for 3.5 s when the song changes or a player appears, on the focused monitor. The island also pops (it widens and glows, then lets go) on those events when it's visible anyway. The control centre never peeks.

   - *Bluetooth* (BlueZ, through Amane's `Bluetooth`): the switch powers the adapter; with bluez installed but stopped it runs `rc-service bluetooth start`. The menu is the same map with the devices bluez knows or finds (it scans while open): connected ones closest, then paired, then the rest. Click to connect, disconnect, or pair (then trust and connect). Pairing and connecting go through a `bluetoothctl` session with its own agent: a PIN or passkey it needs, a code to confirm or to type on the device are asked in a popup, and a failure shows why. Click the bubble to search for devices (`bluetoothctl --timeout 15 scan on`).
   - *VPN*: every openrc service `/etc/init.d/openvpn.*` (here `openvpn.swiss`), each with a switch. Connecting while openrc has it *inactive*, connected once its `up.sh` marks it *started*. A switch runs `rc-service openvpn.<name> start|stop`.
   - *Hotspot* (iwd access point): see [Hotspot setup](#hotspot-setup).
-  - *Ethernet*: every real wired card in `/sys/class/net` (a device behind it, not wireless): connected or no cable, and the link speed it negotiated (`speed`, as 1 Gb/s). A click opens a popup beside the panel with the interface and driver, status (speed, duplex), every IPv4 and IPv6 address, gateway, DNS servers, MAC, MTU and traffic since boot (`ip -o addr`, `ip -o route`, `/etc/resolv.conf`, sysfs). Addresses, gateway, DNS and MAC have a Copy chip; a click anywhere on such a row copies it (addresses without their prefix).

A click turns the panel into its details (it morphs like into any menu; the back button returns): the interface and driver, status (speed, duplex), every IPv4 and IPv6 address, gateway, DNS servers, MAC, MTU and traffic since boot (`ip -o addr`, `ip -o route`, `/etc/resolv.conf`, sysfs). Addresses, gateway, DNS and MAC have a Copy chip; a click anywhere on such a row copies it (addresses without their prefix).
 - **Popups:** questions (a password, PIN or passkey), a code to confirm, a saved password or why something failed, in a small card over the menu. Only a popup with a field takes the keyboard (Enter answers, Escape cancels); the others leave keys to other windows until clicked.
-- **Menus:** one shape the whole way: the panel fades its content out and takes the menu's size (the Wi-Fi and Bluetooth maps are 1100 × 560 px, three times the panel's width, with every other node a ring further in so neighbouring labels don't meet), then the menu's content fades in over it from a window of its own (so the maps' animation redraws only that window). The back button returns to the panel. Moving the pointer off both closes the menu where it is: its content fades out and it shrinks straight into the pill, without the panel growing back first.
+- **Menus:** one shape the whole way: the panel fades its content out and takes the menu's size (the Wi-Fi and Bluetooth maps are 920 × 460 px, with at most 8 networks or devices, the strongest first, every other one a little further in so neighbouring labels don't meet), then the menu's content fades in over it from a window of its own (so the maps' animation redraws only that window).

 - **Sound:** the default output's volume (drag or scroll the slider); the value next to the title is the mute button. With `extra_output` in `shell.conf` a second slider follows for the output whose name contains it (here `NR515`: the `[TX-NR515]` receiver on HDMI 1). Clicking the block elsewhere opens the Sound menu: every output with its own slider and mute; click a name to make it the default output.
 - **Display:** the laptop screen's brightness and the keyboard light (`tpacpi::kbd_backlight`: Off, Low, High), written straight to their sysfs files (a udev rule makes them writable by everyone on this laptop), else through logind, which refuses a shell without a seat (one started over ssh). For external monitors see [External monitor brightness](#external-monitor-brightness).
 - **Performance:** the firmware profiles in `/sys/firmware/acpi/platform_profile_choices` (Low power, Balanced, Performance), and the battery's state and time left. Picking one sets the platform profile and the CPU governor and energy preference with it: Low power = `powersave` + `power`, Balanced = `powersave` + `balance_performance`, Performance = the `performance` governor.
