 ## Changelog
 
+### What was just completed (2026-02-18 session 47)
+- **v0.13.0 — UI Polish Fixes (8 independent fixes):**
+
+  **Fix 1:** backup-status-card border already correct (verified same styling as system-info-card).
+
+  **Fix 2:** Deploy page auto-generated fields now show actual values for deployed apps (`deploy.html`, `handlers.go`). Secrets show as password fields with show/hide toggle; domain/plain values show as readonly text with copy button. JS helpers `toggleAutoField()` / `copyAutoField()` added.
+
+  **Fix 3:** Temperature display made more prominent (`dashboard.html`, `style.css`). Dot enlarged to 11px; value wrapped in colored pill badge (`.temp-value-pill` / `.temp-pill-{green|yellow|red}`).
+
+  **Fix 4:** Dashboard backup card reworked (`dashboard.html`, `handlers.go`). Removed "Mentés most" button and `triggerBackup()` JS. Removed "Tároló méret" line. Added Tier 2 status line (configured/total apps) + warning row for failed cross-drive backups. Handler now computes `CrossDriveTotal`, `CrossDriveConfigured`, `CrossDriveFailed`.
+
+  **Fix 5:** HDD warning banner scoped to dashboard + monitoring pages only (`alerts.go`, `layout.html`, `funcmap.go`). Added `PageOnly []string` field to `Alert` struct. Disk-related warnings (keywords "meghajtón", "adattároló") get stable ID `"disk-not-separate"` + `PageOnly: ["dashboard", "monitoring"]`. `pageMatch()` template function added. Layout renders alerts conditionally.
+
+  **Fix 6:** Tárhely section moved up in Rendszermonitor — now appears right after "Rendszer áttekintés", before "Távoli monitoring" (`monitoring.html`).
+
+  **Fix 7:** Snapshot table improvements (`backups.html`, `style.css`). "MÉRET" renamed to "HOZZÁADOTT (új adat)". `–` for unavailable data replaced with `n/a` (with tooltip explaining restic limitations). New `.col-subtitle` and `.col-na` CSS classes.
+
+  **Fix 8:** Tároló section restructured into tiers (`backups.html`, `handlers.go`, `style.css`). Tier 1 (restic local), Tier 2 (cross-drive, only shown if configured), DB dump directory + total size. Removed "Távoli másolat: Nincs beállítva" placeholder. Handler passes `DBDumpDir`, `DBDumpTotalBytes`, `Tier2Dests` (deduplicated). New `.repo-tier` / `.repo-tier-title` CSS.
+
+  **Files modified (9):** `alerts.go`, `funcmap.go`, `handlers.go`, `templates/style.css`, `templates/dashboard.html`, `templates/backups.html`, `templates/deploy.html`, `templates/monitoring.html`, `templates/layout.html`
