Save/restore cursor (DECSC)
ESC 7 / ESC 8DECSC saves the cursor position and attributes; DECRC restores them. Save:
ESC 7. Restore: ESC 8. Also available as CSI variants: ESC [ s (save) and ESC [ u (restore). The saved state includes cursor position, character attributes, character set, and origin mode. Applications use this to temporarily move the cursor for status updates without disrupting the main content area.How this is testedautomated

\x1b7 (DECSC), move to (5,5), restore with \x1b8 (DECRC), verify cursor returned to col 2, row 0.The same probe runs against headless backends (via Termless) and real terminal apps (via a daemon launched in each terminal). This lets us distinguish parser correctness from rendering correctness.
