Functions

status_bar_open

void status_bar_open(void)

source

This is the only place that moves the cursor. DECSTBM (CSI top;bottom r) shrinks the region that scrolls, and CUP (CSI row; col H) addresses the row left outside it, so the bar stays pinned while log output scrolls above it.

We borrow the line writer for report.h to build the text
