What is new in fob 0.17.1

A small release: the Touch ID prompt now fits the redesigned macOS 27 dialog, and the menu-bar panel gets an opaque backdrop.

### Touch ID prompt, retuned for macOS 27 (#39)

macOS 27 restyled the LocalAuthentication dialog — the separate bold app-name row is gone and the whole reason string is now the **bold headline**, in a narrower window. fob's prompt was written for the old regular-weight body slot, so it turned into a heavy four-line bold block.

The prompt is trimmed, without giving up what makes it an authorization decision rather than a rubber stamp:

```
fob is trying to connect to github-ousson (github.com)
for ssh (pid 10110).
Touch ID to continue with fob.
```

The signing key's name is dropped when it's already the destination alias, and kept when it isn't — notably for `an UNKNOWN destination`, where naming the key matters most. The wording reads fine on macOS 26 too, so there's no version-specific copy.

### Menu-bar panel (#38)

An opaque backdrop behind the panel, so it no longer picks up whatever is behind it.

### Install

```sh
brew install --cask olivierzol/fob/fob
```
