Issue Detail Drawer

A white panel with a compact issue list and a detail drawer. Rows show a status dot, the key, the title, and the assignee. Click a row and a drawer slides in from the right inside the panel while the list dims. It holds a status select, the assignee, labels, a description, and four subtasks with a progress bar: checking one grows the bar and rolls the “2/4” count. Moving to another issue crossfades the content without closing the drawer, and Esc closes it and returns focus to the row. Swap the issues, then drop it into a tracker or a support tool.
