@ -68,8 +68,8 @@ Theme state lives in `ui/src/theme.jsx` — a React context (`ThemeContext`) wit
 `ThemeProvider` that wraps the app in `main.jsx`.

 - **Storage key:** `df_dark` in `localStorage`; falls back to `window.matchMedia('(prefers-color-scheme: dark)')` on first visit
- **Toggle:** button at the foot of the sidebar (`Sidebar.jsx`), and in `BottomNav.jsx` on mobile; the effect writes `localStorage` and toggles the `.dark` class on `<html>`
- **CSS:** `ui/src/index.css` declares semantic tokens under `@theme` (`bg-surface`, `text-ink`, `text-muted`, `border-line`, `text-danger`, …) that resolve to CSS custom properties redefined by `.dark`. **Write components against the tokens, never against literal shades like `bg-white` or `text-gray-400`** — the old per-utility `.dark .bg-white { … }` overrides are gone and must not come back
+- **Toggle:** button in the sidebar header in `App.jsx`; effect writes `localStorage` and toggles the `.dark` class on `<html>`
+- **CSS:** `ui/src/index.css` defines CSS custom properties under `:root` (light) and `.dark`. All Tailwind color overrides are written as `.dark .bg-white { ... }` etc.
 - **Palette:** dark mode uses Perspective's "Pro Dark" colours (`--bg-primary: #242526`, panels `#2a2c2f`, gridlines `#3b3f46`, text `#c5c9d0`)
 - **Perspective viewer:** `Pivot.jsx` calls `viewer.setAttribute('theme', dark ? 'Pro Dark' : 'Pro Light')` on initial load and in a `useEffect([dark])` so the viewer stays in sync when the toggle fires
 - **Consuming the theme:** `import useTheme from '../theme.jsx'` then `const { dark, setDark } = useTheme()`

 **Pages:**

- **Sources** (`SourceList.jsx`) — Lists every source with its constraint fields and a
-  badge for bank feeds; clicking opens it. "New source" opens the create dialog, which can
-  seed fields from a CSV sample or from a linked SimpleFIN account.
+- **Sources** — View and edit source configuration. Shows all known field names and their origins (raw data, schema, rules, mappings). Checkboxes control which fields are constraint fields and which appear in the output view. Supports CSV upload to auto-detect fields.

- **Source detail** (`SourceDetail.jsx`) — The Setup tab, grouped into titled panels:
-  Connection (link/unlink a SimpleFIN account, warns when constraint fields aren't `id`),
-  Fields and view (all known field names and their origins, with checkboxes for constraint
-  fields and view columns), Sample rows, Maintenance (reprocess), and Delete source.
-
- **Bridge** (`Bridge.jsx`) — Every account behind the SimpleFIN credential with balances,
-  the source each maps to, and subtotals split into banking versus retirement (recognised by
-  keyword on the account and institution names). Queries SimpleFIN only when Refresh is
-  pressed. Balances render in accounting style with negatives in parentheses.
-
- **Import** (`ImportHub.jsx`) — Top-level entry point for the frequent job. Lists every
-  source with record counts and last import date, a Sync button for bank feeds, and an
-  upload link for CSV sources.
-
- **Source › Import tab** — Upload a CSV to import records into the selected source. Transformations run automatically on new records. Shows import log with inserted/duplicate counts, expandable key detail, checkbox selection, and delete with confirmation. Sources with `config.simplefin.account_id` also get a Sync panel — a window selector (10/30/45 days or a full backfill) and a "Sync now" button that pulls from the bank API through the same import path.

 - **Rules** — Create and manage regex rules. Live preview fires automatically (debounced 500ms) as pattern/field/flags are edited, showing match results against real records. Rules can be enabled/disabled by toggle.

  See `docs/perspective.md` for the full technical reference on controlling Perspective programmatically.

- **Stacks** — Named unions of multiple sources, each chip linking to its pivot at
-  `/stacks/:name/pivot`. Each stack defines a field mapping (how source fields map to common output columns), an amount field, a date field, and an optional balance offset. The view-data endpoint unions the underlying source views and computes a running balance sorted by date. The Pivot page supports stacks as well as individual sources, with layouts stored in the same `pivot_layouts` table.
