- Updated the resize fast-path repaint to remove the terminal full-screen clear and instead overwrite the viewport in place at home, rewriting each row via `#lineRewriteSequence`. - Passed the viewport width into `#emitResizeViewport` so each row self-clears only its tail with CSI K while resize drag remains active. - Added coverage in `resize-viewport-defer.test.ts` confirming drag-time writes omit ED2/ED3 clears and that ED3 is emitted when the resize settles.
