+        <p>"Accolade Watch" — a polish release focused on desktop integration, visual identity and small quality-of-life fixes.</p>
+        <ul>
+          <li>New matte-vinyl app icon applied across every size (Tauri, Windows Store, Android, Flatpak, tray) plus a monochrome symbolic variant for system trays</li>
+          <li>Window controls can now auto-detect KDE Plasma / Klassy and mirror the system decoration colors and button shape; new full-height-rounded button style added for Klassy's most common look</li>
+          <li>Opt-in "Match system window chrome": QBZ rounds its own corners to the detected desktop's radius (requires app restart — the window is rebuilt transparent so the corners don't show white)</li>
+          <li>Login screen refresh: larger logo, subtle shadow using the theme's muted color, and QBZ / Qobuz™ Player branding under the mark</li>
+          <li>Editor's Picks tab cleanup: removed redundant "Album of the Week" and "Qobuzissime" ribbons on cards inside their own eponymous sections</li>
+          <li>Playlist context menu in the sidebar now flips above the cursor when it would otherwise fall below the window</li>
+          <li>Sort submenu in the sidebar playlists menu no longer gets clipped by its parent dropdown</li>
+          <li>DAC Setup Wizard icon contrast fixed for light accent themes</li>
+          <li>Hardening to audio request signing (internal)</li>
+        </ul>
