/**
 * Repaints from a clean screen when the terminal changes width.
 *
 * A live region is erased by walking the cursor up as many lines as were
 * written. Narrowing the window invalidates that count before it is used: the
 * terminal has already reflowed each of those lines into two rows, so the walk
 * covers half the frame and leaves the top half stranded — one orphaned copy
 * per resize, stacking up above the run.
 *
 * Height changes need none of this. Nothing reflows, the line count still
 * holds, and the renderer's own full clear covers a frame that no longer fits.
 * So this fires on width alone, and the screen is left intact for the resize
 * that does not break it.
