- Status gains reference_updated_at (sourced from reference.db's file
mtime, so it needs no separate persisted state) and the sidebar's
"Your library" panel shows it as a relative "Updated Xh ago" stamp
that self-refreshes every minute.
- Add a Location field to the Library tab's filters panel, wired to the
new LibraryFilter.location.
- Bump every font-size in the stylesheet up one step for a slightly
larger, easier-to-read UI overall.
- Fix the library/deck tile view's +/- quantity overlay permanently
covering the card art's own printed mana cost (top-right corner) —
it now only fades in on hover/focus, like the other row actions.
