The previous SettingsPane.tsx hid 8 unrelated concerns behind 73 "lines"
of JSX where each line ran 400-2000 chars. Reading the file was
infeasible; editing it meant scrolling horizontally through a single
statement spanning every button, modal, and table row.
Split by concern into `settings-sections/`:
SettingsPane.tsx 62 LOC orchestrator
GeneralSection.tsx 94 LOC theme / language / auto-update
ExecutionModeSection.tsx 105 LOC AI CEO ↔ AI Co-Founder toggle
ShortcutsSection.tsx 40 LOC keyboard reference (read-only)
DataSection.tsx 123 LOC update check / backup / restore /
secret backend
SecretsSection.tsx 102 LOC per-company secret bindings
Every file now reads top-to-bottom with normal indentation.
Behavioral changes bundled (they belong with the restructure, not a
separate pass):
- Preferences save model unified: theme already auto-saved on change;
language and auto-update checkbox now do the same. The global
"Save settings" button is gone — there is no longer a state where
a toggled language sits unpersisted waiting for a second click.
- Execution mode card gained a subheader line that names the current
company ("Applies to current company: X"). Multi-company users can
no longer confuse which company they just flipped.
- Auto-updater checkbox gained an inline hint: "Check for application
updates at launch" — the previous naked checkbox never explained
what happens when it is off.
- Restore profile moved into DataSection's backup/restore group,
given `tone="danger"`, and gated behind a `window.confirm` with
copy warning about running work being lost. Backup stays neutral.
The previous layout put Restore in the same 2-col grid as Save +
Check Updates + Backup, making a profile-replacing operation look
as routine as saving a theme preference.
- Secret backend display promoted from a naked text line to a
bordered card so it matches the surrounding section rhythm.
Added i18n keys (zh + en):
settings.updaterHint / settings.modeScope / settings.backupRestore /
settings.restoreConfirm / settings.restoreHint.
Covers J-S1 / J-S6 / S-S1 / S-S2 / S-S3 / S-S4 from the settings audit.
Remaining work (tab sidebar, Providers IA reordering, copy sweep)
lands in follow-up commits.
