FNXC:SourceControl 2026-07-15-20:30:
The global GitLab fallbacks and the global default tracking repo moved out of "General · Global" into their own section, adjacent to "Source Control · Project" under the Integrations nav group. They are integrations with GitHub/GitLab, not general app preferences, and pairing the two scopes is what lets an operator see a global fallback and its project override without hunting across unrelated sections.
NOTE for future edits: `splitSettingsSave` (save-split.ts) gates these nine dual-scope keys on the ACTIVE SECTION ID — they route to the global patch only while this section is open, and to the project patch everywhere else. That guard names `source-control-global` literally. Renaming this section id without updating save-split.ts would silently write these global fallbacks into project settings.

FNXC:SettingsScope 2026-07-15-20:30:
No scope badge on any row here: all nine keys (`gitlabEnabled`, `gitlabInstanceUrl`, `gitlabApiBaseUrl`, `gitlabAuthTokenType`, `gitlabAuthToken`, `githubTrackingDefaultRepo`, `reportRoadmapDedupeEnabled`, `reportRoadmapLabel`, `reportRoadmapRepo`) are declared in BOTH `DEFAULT_GLOBAL_SETTINGS` and `DEFAULT_PROJECT_SETTINGS`, so no badge can state their scope honestly. The section name ("Source Control · Global") carries it, as does each label's "Global …" prefix.

FNXC:SettingsStyling 2026-07-15-20:30:
Plain label+control+help rows use the shared primitives; `gitlabAuthToken` uses the primitive's `type: "password"` (defaulting `autocomplete="off"`). The tracking-repo select and the disclosure chrome stay bespoke — they are custom widgets, not label+control+help rows.
