Tanish Manku a4c3be4c99 PageScene: introduce UndoableAction polymorphism + isReplaying guard
The user critique on the original HistoryManager design was sharp:
adding a new action kind required edits to four places (HistoryContext
interface, deps wiring in editor.ts, entry factory, recorder method).
Anything shared between kinds becomes a chokepoint that grows.

Introduce the proper Command pattern:

- UndoableAction interface — single shape every action class
  implements. HistoryManager's external API becomes record(action) +
  undo/redo. Future kinds add a new class file under
  engine/editor/actions/; HistoryManager itself never grows.
- isReplaying flag — record() no-ops while undo/redo is mid-flight,
  so any side-effect chain inside an action's apply/revert (e.g.
  delete-undo reaching editor.deleteObject which calls
  history.recordDelete) can't poison the stack. Belt-and-suspenders
  with the per-kind silent-setter routes the action classes will use.
- engine/editor/actions/snapshots.ts — shared ObjectSnap /
  TransformSnap types, snapshot helpers, transformsEqual,
  writeTransform, and recreateFromSnapshot. Used by the action
  classes added in the next commit.

Legacy recordCreate / recordDelete / begin+endTransform /
recordSetColor / recordSetLocked / recordSetVisible methods stay as
thin wrappers that bind the current HistoryContext into an
UndoableAction via wrap(). Call sites compile unchanged. They're
removed once all sites migrate to record(new XAction(...)).

The IDE for artists.

ArtCraft

ArtCraft is the IDE for interactive AI image and video creation. We turn prompting into crafting, so your ideas become a form of tangible expression and computing. This is Adobe Photoshop for everyone, and we're giving away the source code!

Show, Don't Tell: Advanced Crafting Features

Text-to-image is great, but artists need control. It's important to know what your image will look like before you generate it, and it's vitally important to achieve consistency and repeatability.

Feature Demo + Explanation
Image to Location Video Placing virtual actors into physical environments establishes single-location consistency. You can film multiple shots within a room without having things disappear.
3D Image Compositing Video Use images (backdrops, foreground elements, props, etc.) in scenes with depth and blend them naturally together. Just a couple of images usually leads to great compositions.
2D Image Compositing Video Use images, background removal, layers, and simple drawing tools to precisely compose a scene.
Image to 3D Mesh Video It's almost impossible to lay out complicated objects or block complicated scenes; turning images into 3D helps position elements exactingly and intentionally.
Character Posing Video You can dynamically pose your characters to achieve the precise character, scene, and camera blocking before calling "action".
Scene Blocking w/ Kit Bashing Video Use 3D asset kits to precisely block out your scene: get the correct angles, object positions, and rich depth layering you can't with text prompting.
Character Identity Transfer Video Use mannequins as simple 3D ControlNets for posing any character.
Background Removal Video Remove backgrounds from images to make them useful in 2D or 3D compositing. They can be props, layers, or backdrops.
Mixed Asset Crafting Video You can use image cutouts, worlds, and simple 3D meshes all together to precisely and intentionally lay out your scenes.

Note: all of the above videos were generated for free with Grok Video; the cost to build this README was negligible.

Quick and Easy Prompting

We haven't abandoned text-to-asset generation for quick prototyping and ideation. We support every popular workflow in a first class fashion.

Feature Demo + Explanation
Text to Image Video Text prompt over a dozen different image models.
Image Editing Video Edit with Nano Banana Pro and GPT Image 1.5.
Image Editing Video Use inpainting, drawing, masking, etc. to edit images.
Image to Video Video Image to video with lots of different options and controls.
Image Inpainting (preview coming soon)
Image Ingredients (preview coming soon)
