Introduce a light/dark MODE axis orthogonal to the existing accent
themes. Neutral surface tokens now live in html[data-mode="light|dark"]
blocks; accent tokens (--primary*, --ring, --chart-1, --sidebar-primary*)
stay in html[data-theme] blocks, so any accent works in either mode.
- globals.css: split neutrals (mode) from accent (theme); add light
palette; dark values unchanged (dark stays the default).
- lib/themes.ts: Mode type, DEFAULT_MODE=dark, MODE_STORAGE_KEY, isMode.
- use-theme.tsx: provider owns mode/setMode/toggleMode + cross-tab sync.
- layout.tsx: boot script applies persisted mode before first paint
(no flash); colorScheme "dark light".
- mode-toggle.tsx (header sun/moon) + themed-toaster.tsx (mode-aware).
- appearance-panel.tsx: light/dark control + updated copy.
- Tokenize hardcoded neutral colors (slate/white/gray) -> semantic
tokens across the app so every surface flips with mode. Flow canvas
and message-bubble timestamps made mode-aware too.

Builds on PR 1's read-only canvas. This PR brings the canvas to ~75%
of list-view parity: drag-to-reposition (persisted) and click-to-edit
via a side panel that mounts the same per-node forms the list view
uses. Drag-to-connect + add/delete from canvas land in PR 2b.
Architecture (the bulk of the diff):
- Extracted the per-node forms (SendButtonsForm, SendListForm,
SendMediaForm, ConditionForm, SetTagForm + inline forms for the
smaller types) plus the shared field components (TextRow,
NextNodeRow, NodeKeySelect) from flow-builder.tsx into
src/components/flows/forms/. Both views now mount the SAME
NodeConfigForm dispatcher so behaviour can't drift between
"what the list editor shows" and "what the canvas side panel
shows".
- Lifted all editor state into a context/hook
(src/components/flows/flow-editor-state.tsx) with a
FlowEditorProvider that wraps both views in flow-editor-shell.
Single source of truth: toggling Canvas ⇄ List never resets
unsaved edits, and a drag on the canvas updates the same nodes
array the list view reads.
- flow-builder.tsx shrinks from ~2400 lines to ~900 (extracted
forms) and stops owning state (now consumes via useFlowEditor()).
List-only UI state — expanded cards, scroll refs, jump-to-node
flash — stays internal.
Canvas additions:
- onNodeDragStop writes the new position to context via
updateNodePosition (flips dirty; serialized in the existing PUT
/api/flows/[id] body — the route already accepts position_x /
position_y per migration 010).
- onNodeClick opens a controlled shadcn Sheet (right-side panel)
with the per-node form, plus "Set as entry" and "Delete node"
buttons. Esc / overlay / close button all close.
What's intentionally still NOT in this PR (PR 2b):
- Per-slot Handle components on the custom node renderer.
- Drag-to-connect handler that maps target → updated
next_node_key for the right slot.
- Floating "+" button to add nodes from canvas.
- Keyboard / context-menu delete.
Tests: 9 new pure-helper tests (uniqueNodeKey + defaultConfigFor
self-consistency). Hook integration tests are deferred — would
require @testing-library/react + jsdom infra. Existing 271 tests
still pass.
