The card's web view no longer resizes during a live pane drag: the stage only rescales, and one reframe runs after the pane holds still, under a snapshot of the last frame that stays up until the piece has painted at its new size. The maxfps cap is gone — the card runs at display rate. Also from the earlier pass: the resting card is the whole viewport composited down rather than a Ken Burns crop, the open card takes the pointer and keyboard, the rock steps aside while it is open, and bios now carries every preserved embedding flag (nolabel, autoreload, maxfps) through the URL rewrite the auto-reload comes back to.
