Two real gaps meant the account-synced zoom (from the previous
"sync through the account" change) never reached the screen:
_load_cache() updated AccountProfileService.preferences but never
emitted profile_changed, so question_player.gd/ccs_service.gd (already
built and listening before login even happens) never found out a
cached value had loaded. And nothing forced a server refresh
right after login - it only fired if the user happened to open the
profile/progress screen, so a fresh device/session had no path to
the true synced value at all.
main.gd now calls AccountProfileService.refresh() once per login
(not on every silent token refresh) so the real preferences GET
always runs right after signing in, on any device.
Also added Question bank/CCS case text size steppers to the Settings
screen next to dark mode, per user request, reusing the same
AccountProfileService/CCSService plumbing as the in-screen A-/A+
buttons.
Local user://settings.cfg meant zoom level didn't follow a student
across devices/browsers. Question bank and CCS text scale now live on
the user's study profile in Mongo (QuestionTextScale/CcsTextScale),
synced through a new PUT /api/profile/me/text-scale endpoint and the
existing preferences GET/cache already used for study preferences.
Both question_player.gd and ccs_service.gd read the synced value at
startup and react to AccountProfileService.profile_changed so a value
pulled down after login (or changed from another session) applies
without a restart. Backend validates the 0.85-1.35 range and updates
only the field(s) provided via a targeted $set, so it can't clobber
the other scale or the unrelated study-profile preferences.
Question bank and CCS case text-size (A-/A+) previously reset to 1.0
on every app launch. Both now load their saved scale from
user://settings.cfg at startup and save on every adjustment, mirroring
the existing pattern used for dark/light mode and sound preferences.
The warning was purely a token-expiry countdown with no concept of
user activity, so it interrupted people who had been clicking through
questions the whole time. AuthState now tracks real input activity
globally and silently refreshes the session in the background when
the user has interacted recently, only surfacing the "Stay logged in?"
dialog for sessions that are genuinely idle. A failed background
refresh still surfaces the dialog rather than silently logging the
user out.
Add real session-history navigation (Previous/Next/Shuffle), compact
side panels, and a segmented progress row to match the mockup layout.
Flashcards now opens straight into Study, with library management
moved into the Options menu ("Manage Flashcards") and Export hidden
from the UI (Import stays). Shuffle is backed by a real, due-before-new
randomized pick on the backend, not a decorative toggle.
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.
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.
