• Make the Codex credit bar actually move as credits deplete. Codex only reports a remaining balance with no total, so there was nothing to draw a bar from and it sat empty while the balance counted down — reading as "nothing used" at exactly the moment you were spending. codemon now remembers the largest balance it has seen and fills the bar as the balance falls below it. A top-up above that mark becomes the new full, and running dry clears it so the next top-up starts from a fresh baseline. If codemon first sees the balance mid-spend it treats that as full, so the bar is only accurate from the next top-up onwards
