| The desktop app draws its own title bar, as Slack and Discord do, and the site can call the app again. | 1 | //! The window's frame. g1t draws its own title bar, as Slack and Discord |
| 2 | //! do, so the window is all g1t and looks the same on every system: on | |
| 3 | //! Windows and Linux the system's frame goes and the bar has the menu | |
| 4 | //! button, back and forward, search, and minimize, maximize and close; on | |
| 5 | //! macOS the bar sits under the window's own traffic lights. The bar | |
| 6 | //! itself is bridge.js's, drawn on every page the window shows, the | |
| 7 | //! site's, the launcher's, and GitHub's while signing in; the site makes | |
| 8 | //! room for it (`--frame-top`, apps/web/app/app.css). Settings can give | |
| 9 | //! the window back its system frame, and the menu bar with it, from the | |
| 10 | //! next start: the bar is a script each window gets as it opens. | |
