The surfaces that hold a single focus and the clock behind it: the FocusBar and its edit, checkpoint, and timeline panels, the queue and backburner that hold what you are not doing yet, and the shift controls that bound the working day. Every string, color, and radius here is lifted from the shipping extension source rather than redrawn.
A focus is one thing you are doing, with a name, a budget, and a clock. This group is the machinery around that idea. FocusBar holds the focus you are on now; FocusQueue and BackburnerDock hold what you are not on yet, which matters because the honest reason a queue exists is that you will be interrupted. The editing surfaces exist because tracked time is only useful if it is true: machines sleep, meetings overrun, and a tracker that cannot be corrected after the fact just teaches you to ignore it.
