### Fullscreen focus mode (desktop + webapp)
- Added a top-right expand icon on every prompt editor that opens a
"Prompt" focus-mode overlay (blurred backdrop, `max-w-4xl` centered
card) for more prompting space.
- Same editor state — overlay binds to the same value + onChange, so
text/@-mentions persist. Auto-focuses with the caret at the end on open.
- Editor fills full height; @-mention dropdown no longer clipped; closes
on Esc / backdrop click.
- Reused `@storyteller/ui-modal`; shared `PromptFullscreenModal` +
button + `useFullscreenPrompt` hook across all 5 desktop promptboxes,
mirrored in the webapp's own PromptBox.
### 3D editor
- Model selector now renders inside the promptbox (was standalone on the
canvas).
- Pose button hides on deselect; pressing "Done" keeps it (flips back to
"Enter Pose Mode") while the character is still selected.
- Drag and drop into folders fix within gallery modal - doesn't close
immediately unless on 3D editor page.
### Tooltips & expand
- Fixed top-left menu tooltips getting stuck open after a tab change.
- Reworked image promptbox auto-grow/expand into a shared
`useAutoGrowEditorHeight` hook (no per-render style writes) with a
smooth height transition.
- Redesigned the gallery modal with a sidebar replacing the old filter
dropdown - filters now show as a list with item counts
- Added a Folders system - create, rename, and delete folders to
organize assets
- Users can drag items onto folders in the sidebar, including
multi-selected items
- Added "Add to Folder" option in the item right-click menu with a
folder picker submenu
- Added "Add to folder" button in the bulk selection bar with a folder
picker popup
- Clicking a folder in the sidebar opens a folder view with its own
content area and empty state
- Folder names are editable - click the title in the header or
right-click a folder in the sidebar to rename
- Videos are now draggable - previously only images and 3D objects could
be dragged
- Folder data is mocked locally for now - ready for API integration
- canvas snapshot aspect ratio is fixed (it was snapshotting only as
squared images)
- added reference/context images in the lightbox under prompt, hovering
shows a larger preview
- added generation details: model used with logo and provider
