+### Added
+- Filmotéka generation now also creates a **"Tipy dne"** folder with **10 random
+  pool movies** (hardlinks; copy-as-is folders like Seriály are excluded). The
+  folder is refreshed each run (`HardlinkManager.generate_random_tips`).
+
+### Fixed
+- Stale **root-level genre folders** were left in the Filmotéka output when the
+  last movie carrying a genre dropped that tag: obsolete-link cleanup only
+  scanned genre folders still present on current movies, so an emptied one was
+  never visited. Cleanup now also sweeps other root-level folders (excluding the
+  grouping roots and `reserved_subfolders` — copy-as-is mirrors, "Tipy dne") and
+  removes the now-empty folder. Grouping folders (Dle roku/…) were already fine.
