+### 3.03d ✅ `[STANDARD]` Registratura — QuickLook Attachment Preview + Bug Fixes (2026-02-28)
+
+**Implementat:**
+
+- ✅ **QuickLook-style preview modal** (`attachment-preview.tsx`, ~480 lines): fullscreen dark overlay cu animații
+- ✅ **Image preview**: zoom with scroll wheel + buttons (25%–500%), pan/drag when zoomed, reset cu tasta 0
+- ✅ **PDF preview**: native browser PDF viewer via blob URL iframe (scroll, zoom, print built-in)
+- ✅ **Multi-file navigation**: săgeți stânga/dreapta (keyboard + butoane), thumbnail strip în josul ecranului
+- ✅ **Actions**: download, print, close (Esc)
+- ✅ **NAS link fix**: `file:///` URLs blocked by browsers — replaced with copy-to-clipboard + "Copiat!" feedback
+- ✅ **NAS card overflow fix**: disabled horizontal scroll on Radix ScrollArea viewport, redesigned card to single-row compact
+- ✅ **Password Vault filter reset**: category/search reset to "all" after add/edit

   - Actions reduced from 3 buttons (close/edit/delete) to 2 (view/edit)
   - Close and Delete moved into detail sheet
   - Column headers have tooltips explaining naming convention
-  - Attachment/thread/deadline indicators compacted in Subject column
+
+- **Bug Fix: NAS `file:///` links don't open Explorer:**
+  - Root cause: all modern browsers block `file:///` URLs from web pages (hard security restriction)
+  - Solution: click-to-copy-to-clipboard with green "Copiat!" badge feedback (2s timeout)
+  - Applied to both detail sheet and entry form
+  - Removed broken `window.open(toFileUrl(...))` calls
+  - **Learning:** `file:///` cannot be opened from web pages — only clipboard copy works
+
+- **Bug Fix: NAS attachment card overflows Sheet boundary:**
+  - Root cause: Radix ScrollArea Viewport has `overflow: scroll` on both axes by default
+  - Fix 1: `overflow-x-hidden` on ScrollArea Viewport via CSS selector override
+  - Fix 2: Redesigned NAS card from two-row layout to compact single-row (filename + NAS badge + Copiază button)
+  - Removed `font-mono` on paths (prevents word-break), removed `shortDisplayPath` (replaced with `pathFileName`)
+
+- **Bug Fix: Password Vault — new entry lands on filtered empty view:**
+  - Root cause: after adding, the module returns to list view but keeps the active category/search filter
+  - Solution: `handleSubmit` now resets `filters.category` to `"all"` and `filters.search` to `""` after save
+
+- **QuickLook-style Attachment Preview (macOS Quick Look inspired):**
+  - New `attachment-preview.tsx` component (~480 lines)
+  - Fullscreen dark overlay (`z-[100]`, `bg-black/90`, `backdrop-blur-sm`) with smooth animations
+  - **Images**: zoomable (scroll wheel + ±buttons, 25%–500%), pannable when zoomed (grab/grabbing cursor), zoom % display, reset with 0 key
+  - **PDFs**: browser native viewer via blob URL iframe (base64→Blob→createObjectURL), with scroll/zoom/print built-in
+  - **Navigation**: left/right arrows (keyboard + circular buttons), bottom thumbnail strip when multiple
+  - **Actions**: download (createElement('a') + click), print (PDF: hidden iframe, image: new window), close (Esc)
+  - **Fallback**: unsupported types show icon + "Download" button
+  - Preview button (Eye icon) shown for images AND PDFs in detail sheet
+  - Replaced old inline image-only preview with fullscreen modal
+  - React 19 compatible: no `setState` in effects, uses `key` prop for remount-based state reset
