## Session 2025-11-21: Canvas Header Polish & Sidebar Icon Replacement

### Session Summary
Completed Phase 4 (Canvas Header) with polished hover states, smooth transitions, and animated button expansions. Replaced all Lucide sidebar icons with custom Figma-exported icons featuring proper default and selected states.

### Changes Made

#### 1. Canvas Header Hover States ✅
**Components Modified:** `BgColorSelector.tsx`, `CanvasSizeSelector.tsx`

**Removed hover animations:**
- Removed text expansion animation on hover from CanvasSizeSelector
- Text labels now only appear when option is selected
- Added subtle `#f0f2f4` hover background to both components

**Updated transitions:**
- Changed from `0.2s` to `150ms ease-in-out` for consistency
- Applied to both background color and canvas size selectors

#### 2. Dimension Text Opacity ✅
**Component Modified:** `CanvasSizeSelector.tsx`
- Set dimension text (e.g., "1200x675") to **80% opacity** for better visual hierarchy
- Improves readability while maintaining design aesthetic

#### 3. Canvas Area Transitions ✅
**Components Modified:** `Canvas.tsx`, `CanvasContainer.tsx`, `CanvasHeader.tsx`

**Canvas transitions:**
- Width and height animate smoothly with `150ms ease-in-out`
- Background color changes instantly (no transition) as requested
- Overflow hidden prevents layout shift during animation

**Container transitions:**
- Added `all 0.15s ease-in-out` transition to canvas container
- Header position adjusts smoothly when canvas size changes

#### 4. Animated Button Expansion ✅
**Component Modified:** `CanvasSizeSelector.tsx`

**Three-part animation system:**
1. **Width expansion/contraction:**
   - Unselected: `minWidth: '38px'` (icon only)
   - Selected: Expands to fit icon + text
   - Transition: `150ms ease-in-out`

2. **Text fade-in/fade-out:**
   - Unselected: `opacity: 0`
   - Selected: `opacity: 0.8`
   - Transition: `150ms ease-in-out`

3. **Text slide-in effect:**
   - Unselected: `translateX(-10px)`
   - Selected: `translateX(0)`
   - Transition: `150ms ease-in-out`

**Implementation details:**
- Text span always rendered (not conditional) to enable smooth transitions
- Button `justifyContent` switches between `center` (unselected) and `flex-start` (selected)
- Padding adjusts dynamically: `9px` unselected, `10px` selected
- All animations synchronized for smooth, professional effect

#### 5. Sidebar Icon Replacement ✅
**New Icon Components Created:**
- `IconLayout.tsx` - Layout/grid icon with default (#545865) and selected (white) states
- `IconText.tsx` - Text "T" icon with default and selected states
- `IconImage.tsx` - Image/photo icon with default and selected states
- `IconHuggy.tsx` - Huggy mascot icon (single state as requested)

**Component Modified:** `Sidebar.tsx`
- Removed Lucide React imports (`Layers`, `Smile`, `Image`, `Type`)
- Replaced with custom Figma-exported icon components
- Icons loaded from localhost Figma MCP server URLs

**Icon Implementation Pattern:**
```typescript
interface IconProps {
  selected?: boolean;
}

export default function Icon({ selected = false }: IconProps) {
  const imgDefault = "http://localhost:3845/assets/[hash].svg";
  const imgSelected = "http://localhost:3845/assets/[hash].svg";

  return (
    <div style={{ position: 'relative', width: '32px', height: '32px' }}>
      <img src={selected ? imgSelected : imgDefault} />
    </div>
  );
}
```

**Huggy Icon Fix:**
- Initially missed `display: 'contents'` CSS property on Face container
- This property makes container transparent in layout, allowing children to position correctly
- Fixed by adding `display: 'contents'` to Face container div

## Session 2025-11-20: Text Editing Bug Fixes

### Session Summary
Fixed critical text editing issues and improved the text feature implementation. The main focus was resolving the missing bounding box problem and improving text editing behavior.

### Issues Addressed

#### 1. Delete Key Behavior ✅
**Problem:** When editing text, pressing Delete/Backspace would delete the entire text object instead of individual characters.

**Solution:** Added context-aware delete key handling in `App.tsx`:
```typescript
// Check if user is editing text
const isEditingText = objects.some(obj => obj.type === 'text' && obj.isEditing);

// Delete selected object (only when NOT editing text)
if ((e.key === 'Delete' || e.key === 'Backspace') && selectedId && !isEditingText) {
  e.preventDefault();
  deleteSelected();
}
```

#### 2. Missing Bounding Box (Critical) ✅
**Problem:** Transformer/bounding box not appearing when text objects were selected. Console showed `Node: undefined` repeatedly.

**Root Cause:** In `Canvas.tsx` line ~286, refs were passed as objects instead of callback functions:
```typescript
// BROKEN:
shapeRef={{ current: shapeRefs.current.get(obj.id) || null }}
```
This created new objects on each render but never actually stored the node references.

**Solution:** Implemented callback ref pattern:
```typescript
// FIXED:
shapeRef={(node: Konva.Node | null) => {
  if (node) {
    shapeRefs.current.set(obj.id, node);
  } else {
    shapeRefs.current.delete(obj.id);
  }
}}
```

**Additional Changes:**
- Updated type definitions in all components to accept both callback and RefObject refs:
  ```typescript
  shapeRef?: ((node: Konva.Node | null) => void) | React.RefObject<Konva.Node>;
  ```
- Updated `TextEditable.tsx`, `CanvasObject.tsx`, and `ImageRenderer` to handle both ref patterns

#### 3. Duplicate/Transparent Text During Editing ✅
**Problem:** Half-transparent text showing behind textarea during editing, creating visual duplicates.

**Solution:** Changed text opacity to 0 during editing in `TextEditable.tsx`:
```typescript
<KonvaText
  // ... other props
  opacity={object.isEditing ? 0 : 1}  // Completely hide during edit
  listening={!object.isEditing}
/>
```

#### 4. Textarea Rendering ✅
**Problem:** Initial attempt to render textarea inside Konva tree caused errors ("Konva has no node with the type textarea").

**Solution:** Moved textarea rendering completely outside Konva tree in `Canvas.tsx`:
```typescript
{editingText && (
  <textarea
    ref={textareaRef}
    value={editingText.text}
    // ... positioned over canvas using fixed positioning
  />
)}
```

### TypeScript Fixes
Fixed multiple TypeScript compilation errors:
- Removed unused imports (`useState`, `getCanvasDimensions`, `KonvaText`)
- Removed unused variables (`editingTextId`, `setEditingTextId`)
- Removed `onTextChange` prop (no longer needed, handled directly in Canvas.tsx)
- Fixed union type handling in `useCanvasState.ts` using `DistributiveOmit` type
- Fixed type assertion in `updateSelected` function

### Files Modified
- `src/App.tsx` - Delete key behavior
- `src/components/Canvas/Canvas.tsx` - Callback refs, textarea rendering, transformer updates
- `src/components/Canvas/CanvasObject.tsx` - Ref handling, removed unused props
- `src/components/Canvas/TextEditable.tsx` - Opacity handling, ref pattern
- `src/hooks/useCanvasState.ts` - DistributiveOmit type, type assertions
- `src/types/canvas.types.ts` - (already had `isEditing` and `isFixedSize` properties)

### Test Results
✅ Build successful without errors
✅ Dev server running at http://localhost:3000/
✅ Bounding box now visible when selecting text objects
✅ Delete key works correctly in both contexts
✅ No duplicate/transparent text during editing
✅ Real-time font size adaptation working
✅ Text position remains stable between edit/view modes

### Current Feature Status
**Phase 9: Text Feature** is now **Core Complete**:
- ✅ Text creation with button and 'T' keyboard shortcut
- ✅ Stage 1: Auto-growing text box on initial creation (68px default font)
- ✅ Stage 2: Fixed-size box with dynamic font scaling after first transform
- ✅ Real-time font size adaptation while typing
- ✅ Transformer/bounding box with blue border and white-filled corner handles
- ✅ Drag, scale, rotate functionality
- ✅ Double-click to edit
- ✅ Context-aware delete key
- ⚠️ Text toolbar (Phase 10) - Still TODO

### Next Session
Start with **Phase 4: Canvas Header** - Implement background color selector and canvas size selector controls.

## Session 2025-11-20 (Continued): Additional Text Feature Refinements

### Additional Issues Fixed

#### 5. Text Scaling on Transform ✅
**Problem:** When scaling up a text object, the font size would revert to default after releasing the mouse.

**Root Cause:** The `fontSize` property wasn't being updated during transformation - only width/height were changing.

**Solution:** Modified `handleTransformEnd` in Canvas.tsx:
```typescript
// Handle text objects: scale fontSize and mark as fixed size
if (obj.type === 'text') {
  // Use the smaller scale factor to maintain readability
  const scaleFactor = Math.min(scaleX, scaleY);
  const newFontSize = Math.max(10, obj.fontSize * scaleFactor);

  return {
    ...updated,
    fontSize: newFontSize,
    isFixedSize: true
  };
}
```

**Behavior:** Font size now scales proportionally with the text box during transformation (minimum 10px).

#### 6. Live Bounding Box Resize While Editing ✅
**Problem:** When deleting letters, the bounding box didn't shrink to hug the content, leaving empty space.

**Solution:** Modified `handleTextareaChange` in Canvas.tsx (lines 166-168):
```typescript
// Always auto-grow/shrink box while editing (live resize)
const newWidth = Math.max(100, tempText.width() + 20);
const newHeight = Math.max(40, tempText.height() + 10);
```

**Behavior:** Text box now dynamically resizes in real-time as you type or delete characters.

#### 7. Cursor Position on Double-Click ✅
**Problem:** When double-clicking text to edit, all text was selected instead of placing cursor at click position.

**Solution:**
1. Added `calculateCursorPosition` helper function in Canvas.tsx (lines 19-55)
2. Updated `handleDoubleClick` in TextEditable.tsx to capture click coordinates
3. Modified textarea focus logic to set cursor at calculated position

**Behavior:** Cursor now appears at the character closest to where you clicked.

#### 8. Text Hint Box Positioning ✅
**Problem:** Text hint box appeared in the middle-right of sidebar instead of next to the Text button.

**Solution:** Repositioned hint box in Sidebar.tsx:
- Moved `relative` positioning to inner sidebar container
- Positioned hint box absolutely with `left-[calc(100%+4px)] bottom-[5px]`
- Added 4px gap between sidebar and hint box

**Behavior:** Hint box now appears directly to the right of the Text button at the same vertical level.

### Files Modified
- `src/components/Canvas/Canvas.tsx` - Text scaling, live resize, cursor positioning
- `src/components/Canvas/TextEditable.tsx` - Capture click coordinates for cursor
- `src/components/Canvas/CanvasObject.tsx` - Updated type signatures for cursor positioning
- `src/components/Sidebar/Sidebar.tsx` - Hint box positioning

### Test Results
✅ Font size scales proportionally when transforming text objects
✅ Bounding box shrinks/grows live while editing
✅ Cursor appears at exact click position on double-click
✅ Text hint box aligned with Text button
✅ All buttons in sidebar maintain consistent width

### Phase 9 Status
**Phase 9: Text Feature** is now **Fully Complete** with all refinements:
- ✅ All core functionality working
- ✅ All edge cases handled
- ✅ All UX improvements implemented

### Next Session
Ready to proceed with **Phase 4: Canvas Header** - Implement background color selector and canvas size selector controls.
