    syncdoom: anchor the sixel image at top-left when terminal pixels are unknown

    Sixel is positioned by text cell, but the image is sized in pixels; on a terminal
    that doesn't report its real cell-pixel size (e.g. xterm with allowWindowOps off)
    the door assumed 16px-tall cells, so the "centered" row landed too low and the frame looked bottom-anchored. When real geometry is unknown, anchor the sixel at
    row 1, col 1 -- predictable, and what a user expects. JXL/PPM (SyncTERM, real geometry) still center via the APC DX/DY offsets.

    syncdoom: cap the text-tier render grid on oversized terminals

    A maximized terminal can measure huge (e.g. 561x105); the text tier then renders
    the full grid -- ~330 KB per frame, 1.5+ MB/s -- which floods the link and trips
    the dead-client watchdog, so the door looks like it auto-terminates. Beyond Doom's own detail the extra cells add only bytes, so cap the text grid to [video] text_max_cols x text_max_rows (default 200x80; 0 = uncapped). Invisible for normal terminals; it only bounds the maximized case.
