Round 10B: tags, ratings and comments

 ## Unreleased
 
+- Files and folders can now carry Meridian tags, a star rating, and a comment: the right-click menu's "Tags & rating…" edits them for the selection (tags and rating apply to every selected item, the comment to a single item), they are kept in Meridian's own local store — never written into the files, so they work for any file or folder — and they show in the pane's preview block.
+
+- The Recycle Bin is now browsable like a folder: a Places entry in the sidebar opens it in a pane, showing every item in the signed-in user's bin across all drives with its original location and deletion time. Items can be restored to where they were deleted from (with the name numbered if something already sits there), deleted permanently after a confirmation, or the whole bin emptied; file operations that cannot apply to recycled items step aside while a pane shows the bin, and a tab left on the bin reopens on it.
+
 - The dark theme is now charcoal with a crimson accent: layered charcoal surfaces (#232323 window, #2B2B2B panels, #333333 raised areas, #404040 borders) replace the near-black ones, the default accent is crimson (#DC143C, listed as "Crimson" in Settings; a saved "Red" choice lands on it), the panel hairlines carry the same crimson, and text on the accent is now white. The red-gray selection, green readouts, and the light theme's surfaces are unchanged.
 
 - Each pane now keeps its own folder tabs, living in the path-bar area: inactive tabs sit as compact chips above the bar, the active tab is the breadcrumb bar itself, and new-tab and close-tab buttons sit at the bar's right end. Every tab remembers its own back/forward history, the session restores both panes' tabs, and the shortcuts are Ctrl+T (new tab), Ctrl+W (close tab) and Ctrl+Tab / Ctrl+Shift+Tab (cycle); middle-clicking a chip closes that tab. Closed tabs are remembered (the last 50, with their history) and Ctrl+Shift+T reopens the most recently closed one.

 Meridian's feature target is KDE's Dolphin, adapted to Windows. Already at parity: dual-pane (split) browsing, per-pane tabs with closed-tab history, clickable breadcrumbs, view modes remembered per folder, a Places-style sidebar, previews, batch rename, sorting and grouping, and content search. The remaining parity work, in planned order:
 
-1. **Virtual locations** — one location layer under the panes, so the Recycle Bin, recent files, search results, and archives browse like folders (builds on Phase 6's archive-as-folder and virtual-view items).
+1. **Virtual locations** — one location layer under the panes, so the Recycle Bin, recent files, search results, and archives browse like folders (builds on Phase 6's archive-as-folder and virtual-view items). _Started: the Recycle Bin browses as a virtual location with restore, permanent delete, and empty._
 2. **Indexed search** — a USN-journal-backed index for instant name search, growing toward content (Phase 4).
 3. **Embedded terminal panel** that follows the current folder (Phase 7).
-4. **Tags, ratings, and comments** stored locally and searchable, with optional NTFS alternate-data-stream storage investigated for portability (Phase 2).
+4. **Tags, ratings, and comments** stored locally and searchable, with optional NTFS alternate-data-stream storage investigated for portability (Phase 2). _Started: tags, ratings, and comments are stored locally and shown in the preview block; searching by them and the ADS investigation remain._
 5. **Network protocols** — SMB browsing first, then optional SFTP, FTP/FTPS, WebDAV, and SCP clients and optional cloud providers, all behind provider interfaces; local file management never depends on them (Phase 6).
 
 Operation undo/redo and Dolphin-style context-menu actions (service menus — the Scripts menu is the seed) round out the program.
