* fix(gotjunk): Fix icon visibility on map with dark backgrounds

Changed all navigation and map control buttons from white backgrounds
to dark gray (bg-gray-800) to fix white-on-white visibility issue
reported by user.

Changes:
- LeftSidebarNav: bg-white/90 → bg-gray-800/90 for all 4 nav buttons
- PigeonMapView: bg-white → bg-gray-800 for zoom/center/legend controls
- White icons now clearly visible on dark backgrounds
- Provides contrast against light map tile backgrounds

Fixes user feedback: "icons no longer display on the map view...
need a lite color background and not white on white"

* fix(gotjunk): Fix classification bug and add duplicate item debugging

Fixed typo bug in handleReclassify where `classification` was used instead
of `newClassification` parameter, causing incorrect discount/bid values.

Added console logging to diagnose duplicate image creation:
- Log when handleClassify is called (new items)
- Log when handleReclassify is called (re-classification)
- Log state updates to track if items are added/updated multiple times
- Log IndexedDB saves to track storage operations

This will help troubleshoot the issue where changing discount/bid creates
duplicate images.

* fix(gotjunk): Add body scroll lock to PigeonMapView

Added missing body scroll lock to PigeonMapView to complete the
fullscreen overlay contract. This prevents Safari from clipping
floating controls when the map is open.

Changes:
- Import useEffect from React
- Lock document.body.style.overflow = 'hidden' on mount
- Restore original overflow on unmount

Completes the z-index fix implementation where all fullscreen
overlays (ItemReviewer, FullscreenGallery, FullscreenViewer,
PigeonMapView) now lock body scroll.

* feat(gotjunk): Adaptive sidebar icon visibility on map view

Fixed low-contrast sidebar icons on varied map tile backgrounds by
implementing context-aware adaptive styling.

Problem:
- bg-gray-800/90 icons invisible on dark map tiles (parks, water, buildings)
- Inconsistent visibility across mixed urban areas (light streets, dark foliage)
- PR #40 fixed white-on-white but created dark-on-dark issue

Solution:
Added getButtonStyle() helper with conditional map-aware styling:
- Map view: Inactive icons use bright bg-indigo-600/85 with strong borders
- Other views: Inactive icons retain subtle bg-gray-800/90
- Active state: Always bright blue (unchanged)

Changes:
- LeftSidebarNav.tsx: Added getButtonStyle() helper function
- All 4 buttons now use helper instead of inline ternary logic
- Preserved Z_LAYERS.sidebar (2200) from PR #40 contract
- No hardcoded z-index values

Result:
✅ Icons visible on light streets, dark parks, blue water, gray buildings
✅ No regression on Browse/MyItems/Cart tabs
✅ Active (blue) distinguishable from inactive (indigo) on map
✅ Build: 413.49 kB │ gzip: 130.10 kB (2.68s)

Pattern learned: UI over dynamic backgrounds needs context-aware styling.

* fix(gotjunk): Ensure sidebar floats above map with pointer events

Added explicit pointer events to PigeonMapView to ensure proper event
handling and confirmed z-index layering is correct.

Z-index contract (already in place):
- Sidebar: Z_LAYERS.sidebar (2200) - highest, always visible
- Map: Z_LAYERS.mapOverlay (1600) - below sidebar

Changes:
- PigeonMapView.tsx: Added pointerEvents: "auto" to map container
- Added missing z-index contract files (constants/zLayers.ts, styles/zindex-map.md)

The sidebar SHOULD float above the map. If not visible in deployed
version, redeploy with latest code from main branch.

* fix(gotjunk): Prevent duplicate item creation race condition

Root Cause:
- handleClassify cleared pendingClassificationItem at END of async function
- If user double-tapped or tap fell through ActionSheet, second call would
  pass guard check before first call completed, creating duplicate items

Fix:
- Added isProcessingClassification flag to prevent concurrent calls
- Clear pendingClassificationItem IMMEDIATELY after guard check
- Wrap processing in try/finally to ensure flag is always reset
- Log processing state for debugging

Impact:
- Eliminates duplicate item creation when:
  * User double-taps classification button
  * Tap falls through ActionSheet backdrop to button beneath
  * User rapidly taps after modifying discount/bid settings

Tested: Build passes (vite build ✓)

* fix(gotjunk): Keep Camera mounted to prevent Chrome permission banner

**Problem**: Chrome on iPhone shows "Camera and microphone access allowed" banner every time map closes

**Root Cause**: BottomNavBar (containing Camera component) was conditionally rendered with `{!isMapOpen && <BottomNavBar />}`
- When map opens → BottomNavBar unmounts → Camera unmounts
- When map closes → BottomNavBar remounts → Camera remounts → `getUserMedia()` called again
- Chrome iOS detects stream reinitialization → shows permission banner

**Safari vs Chrome Behavior**:
- Safari iOS: No banner on remount (more permissive)
- Chrome iOS: Shows banner on every stream reinitialization (stricter privacy UI)

**Fix**: Keep Camera mounted, hide visually with CSS
- Changed from conditional render `{!isMapOpen && ...}` to `style={{ display: isMapOpen ? 'none' : 'block' }}`
- Camera component stays mounted → stream persists → no reinitialization → no banner

**Changes**:
- [App.tsx:708](modules/foundups/gotjunk/frontend/App.tsx#L708): Add `style={{ display }}` prop
- [App.tsx:730](modules/foundups/gotjunk/frontend/App.tsx#L730): Remove closing `)}` from conditional render

**Result**:
- Safari iOS: No banner (same as before) ✓
- Chrome iOS: No banner (fixed!) ✓
- Camera stream persists across map open/close ✓
