- Fix keyboard-nav selection highlight (search results, deck list): the
Discord-styling rewrite dropped the --panel-2 CSS variable it relied
on, so ↑/↓ moved selection but rendered no visible highlight.
- Add click-to-preview: clicking a card thumbnail/tile now opens a
larger centered modal (list and tile views), with a flip button for
double-faced cards' back face. Hover preview is unchanged and clears
when a click-preview opens.
- Add a QtyStepper component (rounded [− N +] pill, with an `overlay`
variant for tile corners) and use it consistently for owned-copy
counts on Add Cards, and the Library list and tile views.
- Add matching +/- steppers to the Library views; decrementing to 0
dims the row for a 5s grace period (still fully interactive) before
it drops out, so an accidental removal can be undone with +.
- Topbar: fill remaining width with the library path (no more premature
truncation), add icons to Open/New Library and Download/Update card
data, and drop the trailing "…" from the library buttons.
