What is new in ShotTessera 0.2.10

## English

- Storyboards now appear progressively: a stable grid is visible immediately, representative frames arrive in order, and sharper captures replace them in place.
- Manual Frame Editor is faster for clear footage while retaining full neighbourhood recovery for motion blur, dissolves, and action-heavy shots.
- Improved editor reliability, accessibility, media-error guidance, and universal-build verification.

## 中文

- 分镜图现在会渐进显示：网格立即出现，代表性画面按顺序填入，再在原位置替换为更清晰的精修画面。
- 手动选帧对清晰素材更快；遇到运动模糊、转场和动作画面时，仍会保留完整的邻域恢复。
- 改进手动窗口可靠性、辅助功能、媒体错误提示与通用构建验证。

## 日本語

- 絵コンテを段階的に表示します。グリッドをすぐに表示し、代表フレームを順に配置した後、より鮮明なフレームへその場で置き換えます。
- 手動フレーム選択は鮮明な素材で高速化しつつ、モーションブラー、ディゾルブ、動きの多い場面では近傍フレームの回復処理を維持します。
- 手動選択ウインドウの信頼性、アクセシビリティ、メディアエラー案内、Universal Build の検証を改善しました。
