hit detection
- Extract shared insertion-indicator.ts for indicator + container highlight
state used by both layout-reorder and drag-into-layout

fillRule 'evenodd' for compound paths with cutouts, transparent fill for
stroke-only icons, strokeUniform to keep stroke width constant
- Text centering: use actual Fabric rendered height (fontSize * lineHeight)
for cross-axis centering instead of declared height
- Hover cursor: use default arrow instead of move/crosshair on elements
- Stream reliability: server sends keep-alive pings every 15s during API TTFT,
forwards thinking_delta events, client resets timeout on ping/thinking chunks
- Remove silent fallback from streamChat to generateCompletion (was causing
double requests when server is unresponsive)
- Add 3-minute timeout to generateCompletion
- AI prompts: instruct model to preserve icon aspect ratios
Implement Figma-style canvas interactions:
- Hover outlines: solid blue on hovered element, dashed on direct children
- Depth-aware selection: single click selects at current depth, double-click
enters containers progressively, Escape exits frame context
- Root frame clipping: depth-0 frames always clip overflowing children
- Drag-out reparenting: dragging a child outside its root frame detaches it
to the overlapping frame or promotes to root level, with undo support
- Layout reorder drag with insertion indicator
- AI design generation with staggered fade-in animation
- Use default cursor on hover instead of move/crosshair
Group consecutive action steps without blank-line breaks between them.
Add width and overflow constraints on assistant message and design
block containers to prevent horizontal overflow.
Polish ActionStepItem with rounded card style, chevron toggle, and
green checkmark for completed steps. Restyle DesignJsonBlock with
consistent card layout, expand/collapse chevron, and nested JSON
preview area.

- Display selected object count in input area for context awareness
- Enhance chat-message with step collapsing and applied state styling
- Expand AI prompts for improved design generation quality
Remove intermediate syncTargetToStore calls during object:moving/scaling/
rotating to avoid excessive store writes during drag. In layout computation,
preserve explicit child coordinates set by user drag instead of overwriting
with auto-layout positions.
Use viewport coordinates (clientX/Y relative to canvas element) instead
of scene coordinates for zoomToPoint. Bump zoom factor from 1.002 to
1.005 for snappier pinch-to-zoom response.
