This pull request updates the design system color tokens and refactors
node and widget component styles throughout the codebase to use new,
more consistent CSS variables. The changes ensure that node and widget
components are styled using unified design tokens, improving
maintainability and theme support for both light and dark modes.
**Design System Token Updates**
* Added new component and node-related CSS variables for background,
border, foreground, and widget states in both light and dark themes in
`style.css`.

* Updated semantic CSS variables to reference the new component/node
tokens for easier usage in components.
* Changed `--secondary-background-hover` to match
`--secondary-background` for improved hover consistency.
**Component Refactoring: Node and Widget Styles**
* Refactored Vue component classes and inline styles to use the new CSS
variables for node backgrounds, borders, and widget states, replacing
legacy variables like `bg-node-component-surface` and
`border-node-component-border` with `bg-component-node-background` and
`border-component-node-border`.

This pull request introduces several improvements to Vue reactivity and
user experience in the graph node and widget system. The main focus is
on ensuring that changes to node and widget data reliably trigger
updates in Vue components, improving drag-and-drop support for nodes,
and enhancing widget value handling for better compatibility and
reactivity.
**Vue Reactivity Improvements:**
* In `useGraphNodeManager.ts`, node data updates now create a completely
new object and add a timestamp (`_updateTs`) to force Vue's reactivity
system to detect changes. Additionally, node data is re-set on the next
tick to guarantee component updates.
[[1]](diffhunk://#diff-f980db6f42cef913c3fe92669783b255d617e40b9ccef9a1ab9cc8e326ff1790L272-R280)

* Widget value composables (`useWidgetValue` and related helpers) now
accept either a direct value or a getter function for `modelValue`, and
always normalize it to a getter. Watches are updated to use this getter
for more reliable reactivity.

* In `useImageUploadWidget.ts`, widget value updates now use a new
array/object to ensure Vue detects the change, especially for batch
uploads.
**Drag-and-Drop Support for Nodes:**
* The `LGraphNode.vue` component adds drag-and-drop event handlers
(`dragover`, `dragleave`, `drop`) and visual feedback (`isDraggingOver`
state and highlight ring) for improved user experience when dragging
files onto nodes. Node callbacks (`onDragOver`, `onDragDrop`) are used
for custom validation and handling.

**Widget and Audio Upload Handling:**
* In `uploadAudio.ts`, after uploading an audio file, the widget's
callback is manually triggered to ensure Vue nodes update. There is also
a commented-out call to mark the canvas as dirty for potential future
refresh logic.
[[1]](diffhunk://#diff-796b36f2cafb906a5e95b5750ca5ddc1bf57a304d4a022e0bdaee04b4ee5bbc4R61-R65)

These changes collectively improve the reliability and responsiveness of
UI updates in the graph node system, especially in scenarios involving
external updates, drag-and-drop interactions, and batch widget value
changes.

Summary
- Add comprehensive telemetry for key UI interactions using existing
telemetry hooks (cloud-enabled, no-op in OSS):
Sidebar and top-level
- Node library button: `node_library`
- Model library button: `model_library`
- Workflows button: `workflows`
- Assets/Media button: `assets`
- Templates button: `templates`
- Keyboard Shortcuts: `keyboard_shortcuts`
- Console: `console`
- Help Center: `help_center`
- Settings (from Comfy logo menu): `settings_menu`
Floating canvas menu
- Minimap toggle: `minimap_toggle`
- Hide links toggle: `hide_links`
Run button and queue
- Run button handle (drag): `run_button_handle`
- Run mode selection: `run_instant`, `run_on_change`
- Queue multiple: `queue_multiple` fires on each run when batch count >
1 (moved from batch-count-change to run-time, per guidance)
Error dialogs
- Close (X/mask/ESC): `error_dialog_close` via dialog onClose
- Show report: `error_show_report`
- Help fix this: `error_help_fix_this`
- Find issues: `error_find_issues`
Nodes / Subgraphs
- Selection toolbox “Node info”: `node_info`
- Enter subgraph (node header enter): `open_subgraph`
- Subgraph breadcrumb navigation: `subgraph_breadcrumb_item` and
`subgraph_breadcrumb_root`
Settings / Credits / Search
- Settings menu button (under Comfy logo): `settings_menu`
- Purchase credits (Settings > Credits panel): tracked via existing
`trackAddApiCreditButtonClicked`
- Purchase credits (Avatar popover Top Up): tracked via existing
`trackAddApiCreditButtonClicked`
- Debounced search telemetry already present for node search and
template filters; left as-is
Notes and answers
- Error dialog onClose: only fires when the dialog actually closes (X,
mask, ESC, or programmatic close). “Show report” and “Help fix this” do
not close the dialog; they each emit their own events.
- Telemetry is behind the cloud provider; calls are optional
(`useTelemetry()?.…`). OSS builds send nothing.
Open questions / follow-ups
- Primary Run button click: today cloud-only `trackRunButton` exists; we
can also emit a UI-level `run` click (`UI_BUTTON_CLICKED` style)
alongside it if desired. Confirm preference and I can add it.
- Subgraph usage richness: if we want structured analytics (e.g.,
action, depth, subgraph id, node count), I can add a dedicated provider
method and include richer metadata at enter/breadcrumb.
- Optional parity: track the Comfy menu’s “Browse Templates” item in
addition to the sidebar Templates button.
Quality
- Ran `pnpm lint:fix` and `pnpm typecheck`; both pass locally.
Implementation details
- All handlers refactored to named functions where needed; used `void`
for intentionally unawaited async calls per lint rules.
- Event names kept consistent in `button_id` strings; happy to align to
a different naming scheme if you prefer.

## Summary
Enables Vue nodes to resize from all four corners and consolidated the
interaction pipeline.
## Changes
- **What**: Added four-corner handles to `LGraphNode`, wired them
through the refactored `useNodeResize` composable, and centralized the
math/preset helpers under `interactions/resize/` with cleaner pure
functions and lint-compliant markup.
## Review Focus
Corner-to-corner resizing accuracy (position + size), pinned-node guard
preventing resize start, and snap-to-grid behavior at varied zoom
levels.

## Summary
Fixed Vue node opacity calculation to properly combine global opacity
setting with muted/bypassed state opacity.
**Root Cause**: When global opacity setting was added as inline style
(481aa8252), it began overriding CSS `opacity-50` classes due to higher
specificity.
**Solution**: Modified `nodeOpacity` computed property to calculate
effective opacity as `globalOpacity * 0.5` for muted/bypassed states,
removing conflicting CSS classes.
## Changes
- **What**: Fixed [CSS specificity
conflict](https://developer.mozilla.org/en-US/docs/Web/CSS/Specificity)
where inline `opacity` style overrode `opacity-50` classes for
muted/bypassed nodes
- **Breaking**: None - restores intended opacity behavior
## Review Focus
Multiplicative opacity calculation ensuring muted/bypassed nodes apply
0.5 opacity on top of global opacity setting rather than being
overridden by it.

## Summary
Fixes issue where node size changes are not serialized by routing
DOM-driven node bounds updates through a single CRDT operation so Vue
node geometry stays synchronized with LiteGraph.
## Changes
- **What**: Added `BatchUpdateBoundsOperation` to the layout store,
applied it via the existing Yjs pipeline, notified link sync to
recompute touched nodes, and covered the path with a regression test
## Review Focus
Correctness of the new batch operation when multiple nodes update
simultaneously, especially remote replay/undo scenarios and link
geometry recomputation.

## Summary
Replace color/dark-color pairs in components with design tokens to allow
for easy overriding.
<!-- Also standardizes the icon pattern to simplify the tailwind config.
-->
## Changes
- **What**: Token based colors, for now, mostly.
- **Breaking**: Got approval from Design to collapse some very similar
pairs of colors that seem to have diverged in implementations over time.
Some of the colors might be a little different, but we can tweak them
later.
## Review Focus
Still have quite a few places from which to remove `dark-theme`, but
this at least gets the theming much closer.
Need to decide if I want to keep going in here or cut this and do the
rest in a subsequent PR.

The third PR for managing display of widgets on subgraph nodes. This is
the one that actually makes the functionality usable and user visible.
Adds
- A right-side modal for configuring which widgets are promoted,
accessed by right click or selection toolbar
- This menu allows for re-arranging widget order by dragging and
dropping.
- Indicators inside the subgraph for which widgets have been promoted.
- Context menu options for promoting or demoting widget inside of a
subgraph.

Known issues
- Some preview widgets are not added to a node until a draw operation
occurs. The code does not yet have a way of determining which nodes
should have draw operations forced to facilitate initial widget
creation.

by [Unito](https://www.unito.io)
## Summary
Fixes two errors with subgraph progress states:
1. Nodes inside subgraphs were not having progress state shown
2. Subgraph nodes (outer representation) themselves did not have a
visible progress state
1 is fixed by using locator IDs instead of local node IDs.
2 is fixed by ensuring the subgraph title button does not wrap to a
newline and thus block the progress bar under the node header.
## Changes
- **What**: Updated `useNodeExecutionState` composable to use
`nodeLocatorId` for tracking execution state across subgraph boundaries
- **What**: Modified NodeHeader layout to fix subgraph enter button
positioning with proper flexbox gap
## Review Focus
Execution state tracking accuracy for nested subgraph nodes and
NodeHeader layout consistency across different node types.

## Summary
Error states were not getting propagated down to the InputSlots from the
API Repsonse
I created a provider and injected error state. It seemed like a way
better idea than prop drilling or building a composable that only two
nodes (`InputSlot` and `OutputSlot`) would need.
## Changes
The follow are now error code red when an input node has errors:
1. There's a error round border around the dot.
2. The dot is error colored.
3. The input text is error colored.
This treatment was okay after feedback from design.

This pull request refactors and improves the "More Options" popover
functionality for graph nodes in the UI. The main change is a rename and
redesign of the menu component from `MoreOptions` to `NodeOptions`,
introducing a global singleton pattern for popover control and enabling
context menu support on node right-click. This results in better
maintainability, more flexible triggering, and improved user experience.
**Node Options popover refactor and global control:**
* Renamed and refactored `MoreOptions.vue` to `NodeOptions.vue`,
removing the embedded button and exposing imperative methods (`toggle`,
`hide`, `isOpen`) for external control. The component now
registers/unregisters itself globally via `registerNodeOptionsInstance`.

* Added `NodeOptionsButton.vue` as a dedicated button component for
triggering the popover, decoupling the button UI from the popover logic.
* Implemented a global singleton pattern in `useMoreOptionsMenu.ts` for
controlling the `NodeOptions` popover from anywhere, with
`toggleNodeOptions` and `registerNodeOptionsInstance` functions.

**UI integration and event handling improvements:**
* Updated `SelectionToolbox.vue` to use the new `NodeOptionsButton`
instead of the previous embedded `MoreOptions` button, and added the
`NodeOptions` popover to the main `GraphCanvas.vue` template for global
accessibility.

the node options popover at the cursor position and integrating with

## Summary
I want to take a more general look at `comfyApp.graph.onTrigger` but
this is the cleanest fix I could come up with for #5694.
I will explore simplifying onTrigger in a separate PR.
## Changes
1. Create a `node:slot-errors:changed` trigger.
2. Trigger it if we find any of the node slots have errors.
3. Check each node to see if there is any error present.
4. Add an error class if there are.
## Screenshots (if applicable)
Working error states!

## Summary
Replaced reactive (Vue-based) widget LOD with CSS visibility control.
Performance doesn't dramatically improve, but we avoid the mount/unmount
overhead during zoom/pan operations. This PR implements the visual
component of LOD—complex widgets that need lifecycle management will be
addressed separately.
### Problem & Solution
Problem: we want LOD to improve rendering performance and visual
feedback but discovered using reactivity in the current setup for it
meant mounting/unmounting caused worse lag than the performance it aimed
to fix. Switching to render all the details all the time but using css
visibility proved to be the best solution. However, it doesn't improve
rendering performance by much because the GPU texture size is the
bottleneck (from TransformPane.vue CSS transforms) and not
rasterization.
Solution: Keep all nodes/widgets mounted, use CSS visibility: hidden for
LOD. Trade memory for performance stability during zoom/pan/drag
operations.
### Technical Decision
We chose Performance > Memory:
- CSS transforms create a single GPU texture whose size depends on node
count, not widget complexity
- Mounting/unmounting hundreds of widgets during zoom = noticeable lag
from Vue VDOM diffing (since all components are mounted all the time
because of viewport culling challenge/trade off see
https://github.com/Comfy-Org/ComfyUI_frontend/pull/5510.)
- CSS visibility changes = no reactivity overhead, smooth interactions
- Result: Similar performance, but without interaction stutters
This is the visual layer only. If we want a hook into the LOD state per
node / widget that would be the next follow up system to implement.
### Next Steps (maybe)
- Chunked (split up single Transform Pane transform layer) when
rendering 1000+ nodes (maybe)
- ~~Selective unmounting API for widgets that register as "expensive"~~
- ~~Client bound hydration system~~

## Summary
Don't route events up through GraphCanvas if the component itself can
handle the changes
## Changes
- **What**: Reduce the indirect access or action dispatch to
composables/stores.
## Review Focus
The behavior should be either equivalent or a little snappier than
before. Also, the local state in LGraphNode has (almost) all been
removed in favor of reacting to the nodeData prop.

## Summary
Prerequisite refactor/cleanup to use a global store instead of having
nodes throw up events to a parent component that stores a reference to a
singleton service that itself bootstraps and synchronizes with a
separate service to maintain a partially reactive but not fully reactive
set of states that describe some but not all aspects of the nodes on
either the litegraph, the vue side, or both.
## Changes
- **What**: Refactoring, the behavior should not change.
- **Dependencies**: A type utility to help with Vue component props
## Review Focus
Is there something about the current structure that this could affect
that would not be caught by our tests or using the application?

## Summary
Added tooltip support for Vue node components using PrimeVue's v-tooltip
directive with proper data integration and container scoping.

## Changes
- **What**: Implemented tooltip functionality for Vue node headers,
input/output slots, and widgets using [PrimeVue
v-tooltip](https://primevue.org/tooltip/) directive
- **Dependencies**: Leverages existing PrimeVue tooltip system, no new
dependencies
## Review Focus
Container scoping implementation via provide/inject pattern for tooltip
positioning, proper TypeScript interfaces eliminating `as any` casts,
and integration with existing settings store for tooltip delays and
enable/disable functionality.

## Summary
Integrated Vue node components with canvas panning mode to prevent UI
interference during navigation.
## Changes
- **What**: Added
[canCapturePointerEvents](https://docs.comfy.org/guide/vue-nodes)
computed property to `useCanvasInteractions` composable that checks
canvas read-only state
- **What**: Modified Vue node components (LGraphNode, NodeWidgets) to
conditionally handle pointer events based on canvas navigation mode
- **What**: Updated node event handlers to respect panning mode and
forward events to canvas when appropriate
## Review Focus
Event forwarding logic in panning mode and pointer event capture state
management across Vue node hierarchy.

This pull request improves the selection toolbox behavior during node
dragging by ensuring that it correctly responds to both LiteGraph and
Vue node drag events. The main changes introduce a reactive drag state
for Vue nodes in the layout store and update the selection toolbox
composable and Vue node component to use this state.
**Selection toolbox behavior improvements:**
* Added a helper function and separate watchers in
`useSelectionToolboxPosition.ts` to hide the selection toolbox when
either LiteGraph or Vue nodes are being dragged. This ensures consistent
UI feedback regardless of node type.

**Vue node drag state management:**
* Added a reactive `isDraggingVueNodes` property to the
`LayoutStoreImpl` class, along with getter and setter methods to manage
Vue node drag state. This allows other components to reactively track
when Vue nodes are being dragged.

* Updated `LGraphNode.vue` to set and clear the Vue node dragging state
in the layout store during pointer down and up events, ensuring the
selection toolbox is hidden while dragging Vue nodes.

**Dependency updates:**
* Imported the `layoutStore` in `LGraphNode.vue` to access the new drag
state management methods.
* Added missing `ref` import in `layoutStore.ts` to support the new
reactive property.
