chore: release v0.27.23

Filled, with a hairline white edge — the same trick the home marker
uses. A ring is an outline drawn over whatever is beneath it, and eight
pixels of one over the satellite imagery was barely visible, which is
the whole reason the layer exists to be looked at.

Its own colour, in its own key, beside the switch that turns the layer
on. Separate from the decode colour deliberately: that one exists
because the band palette disappears over some basemaps, and cyan over a
pale sea has exactly the same problem for exactly the same reason. One
control for both would have forced the two layers into a single colour,
which is the distinction it took a shape to draw in the first place.

The picker only appears while the layer is on, since it configures that
layer and nothing else, and it is a portable UI pref like the other map
colours, so it travels with data/.

+# Building OpsLog on Linux
+
+OpsLog is developed on Windows. The Linux build shares every line of the
+frontend and all but a handful of Go files; what differs is listed at the bottom
+of this page.
+
+**It cannot be cross-compiled from Windows.** Wails links against the system
+WebKit on Linux, which needs cgo and the GTK/WebKit headers, so the binary has
+to be produced on a Linux machine (or a container). What *can* be checked from
+Windows — and is, at every release — is that the Go half still compiles:
+
+```bash
+GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go build ./...
+GOOS=linux GOARCH=amd64 CGO_ENABLED=0 go vet ./...
+```
+
+## The short way
+
+```bash
+./scripts/linux-setup.sh
+```
+
+It checks everything below, prints the one install command your distribution
+needs if something is missing, and builds when nothing is. The rest of this page
+is what it checks, for when you would rather do it by hand.
+
+## Dependencies
+
+```bash
+# Debian / Ubuntu
+sudo apt install build-essential pkg-config libgtk-3-dev libwebkit2gtk-4.1-dev nodejs npm
+
+# Fedora
+sudo dnf install gcc-c++ pkgconf-pkg-config gtk3-devel webkit2gtk4.1-devel nodejs npm
+
+# Arch
+sudo pacman -S base-devel pkgconf gtk3 webkit2gtk-4.1 nodejs npm
+```
+
+**Go and node do not come from the package manager.** No current distribution
+ships a Go new enough for `go.mod` (Ubuntu 24.04 / Mint 22 have 1.22, Ubuntu
+22.04 / Mint 21 have 1.18), and Ubuntu 22.04 / Mint 21 ship node 12 where Vite
+needs 18. Both are the usual reason a first build fails with an error that
+points somewhere else entirely:
+
+```bash
+# Go, from go.dev
+wget https://go.dev/dl/go1.25.1.linux-amd64.tar.gz
+sudo rm -rf /usr/local/go && sudo tar -C /usr/local -xzf go1.25.1.linux-amd64.tar.gz
+echo 'export PATH=/usr/local/go/bin:$HOME/go/bin:$PATH' >> ~/.profile   # log out and back in
+
+# node 20, only if `node -v` is below 18
+curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash - && sudo apt install nodejs
+```
+
+Then the Wails CLI:
+
+```bash
+go install github.com/wailsapp/wails/v2/cmd/[email protected]
+wails doctor          # says what is still missing
+```
+
+`libwebkit2gtk-4.0` also works; pass `-tags webkit2_40` to `wails build` if your
+distribution only has the older one.
+
+## Build
+
+```bash
+wails build           # → build/bin/OpsLog
+./build/bin/OpsLog
+```
+
+`wails dev` works the same as on Windows.
+
+## Runtime requirements
+
+- **PulseAudio or PipeWire** for the voice keyer, the QSO recorder and the CW
+  decoder. PipeWire is fine — OpsLog speaks the PulseAudio protocol, which
+  `pipewire-pulse` answers. Without a sound server those three features report
+  "cannot reach the sound server" and everything else works normally.
+- **Serial port access** for CAT, keyers, rotators and amplifiers. Ports appear
+  as `/dev/ttyUSB0`, `/dev/ttyACM0`… and on most distributions belong to the
+  `dialout` group:
+
+  ```bash
+  sudo usermod -aG dialout $USER      # log out and back in
+  ```
+
+  This is the single most common reason a rig that works in WSJT-X shows
+  "permission denied" in OpsLog.
+- **TrustedQSL** (`tqsl`) for LoTW uploads, from your package manager. OpsLog
+  finds it on `PATH`.
+
+## Where OpsLog keeps its data
+
+Next to the binary, in `data/` — the same portable layout as on Windows, so a
+folder in your home directory carries the logbook with it.
+
+If the binary sits somewhere you cannot write (`/usr/bin`, `/opt`), OpsLog uses
+`~/.local/share/OpsLog/data` instead and says so in `startup.log`. The startup
+log itself lives in `~/.cache/OpsLog/startup.log`.
+
+## What is different from the Windows build
+
+| | |
+|---|---|
+| **OmniRig** | Not available — it is Windows COM automation. Use a native backend instead: Icom CI-V (USB and network), Yaesu, Kenwood/Elecraft, FlexRadio, TCI, Xiegu. |
+| **Denkovi USB relay** | Not available — it needs FTDI's `ftd2xx.dll`. The other relay backends work. |
+| **Audio** | PulseAudio/PipeWire instead of WASAPI. Same devices, same fixed 16 kHz mono format. |
+| **Auto-update** | Works, and is simpler: Linux lets a running binary be replaced, so none of the Windows deferred-swap machinery is needed. |
+| **Window placement** | OpsLog cannot read the monitor layout, so a saved window position is always trusted rather than clamped onto a visible screen. |
+| **Single instance** | An `flock` on `$XDG_RUNTIME_DIR/OpsLog/instance.lock` instead of a named mutex. It cannot raise the existing window, only refuse to start a second one. |
