Study card: label the answer and "key takeaway" as distinct sections
with a real visible divider (previously an all-but-invisible
HSeparator) instead of one undifferentiated block of text. Also fixes
a real gap where a cloze card's extra field was silently dropped,
since only basic notes combined answer+extra into one label. Bigger
card, gradient Show-Answer button matching the app's signature CTA
style instead of a duller flat teal, and the Undo button now hides
itself when there's nothing to undo instead of sitting there disabled
looking identical to a real action.
Library: colored type badge per card (Basic/Cloze) instead of plain
gray text, more breathing room inside each row, Study promoted to the
same gradient CTA style, and Edit/Archive given a real secondary
button treatment instead of default theme buttons. Note editor fields
renamed ("Back / Extra takeaway" + a separate "Extra" field was
genuinely confusing) and now show which deck a card is being saved to.
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.
current_study_day_start_utc() passed use_space=true to
Time.get_datetime_string_from_unix_time(), producing "2026-07-21
00:00:00Z" (space separator) instead of ISO-8601. The server's
System.Text.Json DateTime converter rejects that with a 400, which
the client surfaces as a generic "could not be loaded" error -
blocking every study session. Confirmed against the live API: the
space-separated value 400s, the corrected T-separated value returns
a card.
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.
