Log Message:
syncalert: TODO note 640x384 downscale + the DECSSDT status-line fix

The engine is 640x400 (80x25) but SyncTERM defaults to an 80x24 / 640x384
canvas (its status line takes the 25th row), so every image tier downscales
0.96x and RA's single-pixel vertical bars drop -- text/gauges degrade;
crisp only at a true 640x400. Record the proper fix inline: drop the status
line with DECSSDT (CSI 0 $ ~), first saving the client's current setting via
DECRQSS (DCS $ q $ ~ ST) so door exit can restore it. Notes the separate,
smaller one-row sixel reserve too.
