 ## [Unreleased]
 
+### Changed
+- Bundled Inter Regular, SemiBold, and Bold font assets so Windows uses consistent Latin UI typography without depending on an installed UI font, with `Yu Gothic UI` and `Meiryo` retained as Japanese fallbacks.
+
+### Fixed
+- The Create button now uses the same rounded two-pixel focus border as the Command and Search fields without shifting its content.
+- Compact Create and window-caption button tooltips now optically center their text vertically.
+- macOS and Linux retain their platform font stacks instead of inheriting the Windows-targeted embedded Inter family, preventing unsupported characters from rendering as missing-glyph boxes.
+

 ## Overview
 Praxis v2 is an Avalonia desktop launcher migration. The app uses strict-MVVM Core models with model-owned launcher button state, a pseudo-acrylic frameless resizable shell, command execution with suggestions, search, free-positioned launcher buttons on a dynamically sized placement surface, a persisted Dock promoted only from placement-area launcher-button clicks, a model-driven status bar, SQLite-backed launcher persistence, launch logging, button editing, drag/multi-select operations, file-backed launcher-button sync, and basic desktop command/default-app execution. When the Praxis window becomes active, the Command field is focused automatically so command execution is ready immediately.
 
+On Windows, the shell embeds the Inter typeface for consistent Latin UI typography and falls back to `Yu Gothic UI` or `Meiryo` for characters Inter does not cover. macOS and Linux keep their platform font stacks.
+
 The former .NET MAUI app project has been removed. Existing v1 launcher databases remain readable through the shared data layer: v2 uses the existing `praxis.db3` file when present, also accepts an existing `praxis.db`, and migrates launcher-button schema to version 5. Theme mode switching is available in the Avalonia shell; persisted theme settings and runtime error-log writes remain migration follow-up work.

 ## 概要
 Praxis v2 は Avalonia へのデスクトップランチャー移行版です。strict MVVM の Core model がランチャーボタン状態を所有し、擬似アクリル風のリサイズ可能なフレームレス shell、候補付き Command 実行、Search、動的に広がる配置面上の自由配置ボタン、配置領域のランチャーボタンクリックからだけ昇格する永続化 Dock、Model 駆動のステータスバー、SQLite 永続化、launch log、ボタン編集、ドラッグ/複数選択操作、ファイルベースの launcher-button 同期、基本的なデスクトップコマンド/既定アプリ起動を持ちます。Praxis ウィンドウがアクティブになると Command 欄へ自動フォーカスし、すぐに Command 実行できる状態にします。
 
+Windows では英数字 UI の typography を揃えるため、shell に Inter typeface を埋め込みます。Inter が持たない文字は `Yu Gothic UI` または `Meiryo` へ fallback します。macOS と Linux はそれぞれの platform font stack を維持します。
+
 旧 .NET MAUI アプリプロジェクトは削除済みです。既存 v1 の launcher DB は共有 data layer から読み込めます。v2 は既存の `praxis.db3` を優先し、既存の `praxis.db` も受け入れ、launcher button schema を version 5 へ移行します。Avalonia shell ではテーマモード切り替えを利用できます。テーマ設定の永続化と runtime error-log 書き込みは今後の移行対象です。
