When a lot number or other AI value is long, the composite text label (e.g. "(17)251231(10)VERYLONGLOT") could be wider than the GS1 DataBar symbol. `injectCompositeText` now estimates text width using Courier New monospace metrics (~0.6em/char) and expands the SVG viewBox/width when necessary, centering the barcode within the wider canvas.

レビュー指摘対応。 - OutputField の className/statusClassName/textareaClassName の 3 つの エスケープハッチを単一の fill prop に置換し、内部 DOM 3 層へのレイアウト クラス付与をコンポーネント内にカプセル化（#2） - fill 時は手動リサイズ(resize-y)と h-full の競合を避けるため resize-none を 強制し managed height を保証（#3） - エラー表示で入力カラムが伸びても items-stretch で左右カラム高さが揃うことを 検証する E2E を追加。旧実装(items-start)で fail する陽性対照を確認済み（#4） - 既存「デスクトップ幅で揃う」テストの許容値に根拠コメントを付与（#5） Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
