- Favorites: star toggle on course rows, the course page, and a new
dashboard card; rebased on rename/move, backed up/restored, and
caught by stale-reference cleanup (also fixed a pre-existing gap
where favorites.json wasn't in the backup file list).
- Storage Usage: click a folder row to drill into its contents one
level at a time, with a Back button.
- Lesson player: added ,/. (speed step), [/] (prev/next lesson), and
F (fullscreen) keyboard shortcuts.
- Settings: a CHANGELOG.md-backed "What's New" list, since VERSION
alone only ever shows the current build.
