They only closed via their own trigger button or a menu item -
clicking outside, pressing Escape, or opening the other dropdown
while one was open left it stuck on screen (confirmed opening both
stacked on top of each other). Add a shared invisible backdrop
(mirroring main.gd's drawer-backdrop pattern) that closes whichever
dropdown is open on outside click or Escape, and have opening one
close the other first.
The panel's shared Brand.panel_box background is ~80% opaque, which
compounded with the dialog's own dim backdrop let the screen behind
show through and washed out the card against it. Force full opacity
on this dialog's panel specifically, since other panel_box overlays
still rely on the shared translucency.
Import and export were stubbed with status-text placeholders; wire them
to the existing backend endpoints with a real file picker (web JS
bridge or native FileDialog) and browser/desktop download, plus an
import preview with create/update/skip/error counts before commit.
Also fix the library and study screens' theme-refresh handlers, which
were no-op stubs so cards never restyled on a theme toggle, and add
responsive layout handling for narrow viewports.
Adds a full flashcards system: FSRS-based scheduling, cloze/basic
card types, CSV import/export, media storage, and study UI, wired
into navigation and the dashboard alongside existing question flows.
