Implement comprehensive edge-to-edge rendering across Teacher, Parent, Student apps and shared libraries, fixing all layout overlaps and inset handling issues. **Teacher App:** - Fix StudentContextFragment and FileListFragment crashes (LayoutParams type mismatch - RelativeLayout vs CoordinatorLayout) - Add edge-to-edge for 40+ fragments including CourseSettings, QuizList, DiscussionsList, FileSearch, PostPolicy, CommentLibrary, Profile, SpeedGrader fragments, and more - Fix FAB insets across all fragments with correct LayoutParams types - Update 50+ XML layouts with proper toolbar height handling (wrap_content + minHeight pattern) **Parent App:** - Fix DashboardFragment toolbar insets - Add FAB insets to CourseDetailsScreen and ManageStudentsScreen (Compose) - Fix edge-to-edge for QrPairing, AnnouncementDetails, Alerts, AlertSettings, Courses, and CreateAccount screens **Student App:** - Update night mode styles for edge-to-edge compatibility **Shared Libraries:** *pandautils:* - Add edge-to-edge for DiscussionDetailsWebViewFragment, LtiLaunchFragment, AssignmentDetailsFragment - Fix InboxFragment FAB insets with programmatic CoordinatorLayout handling - Fix InboxDetailsScreen Compose toolbar overlap with status bar insets - Fix TriStateBottomSheet navigation bar overlap in SpeedGrader - Remove unnecessary Scaffold padding in SpeedGraderContentScreen - Update theme values for edge-to-edge compatibility *login-api-2:* - Add edge-to-edge for all login activities (FindSchool, LandingPage, SignIn, LoginWithQR, AcceptableUsePolicy) - Update login activity layouts with proper toolbar height handling - Update theme styles for edge-to-edge Key patterns implemented: - Toolbars: applyTopSystemBarInsets() + wrap_content + minHeight - Scrollable content: applyBottomSystemBarInsets() - FABs: Manual insets with correct LayoutParams type matching parent container - Compose: windowInsetsPadding() + contentWindowInsets = WindowInsets(0,0,0,0) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <[email protected]>

This commit completes the edge-to-edge rendering implementation across
all apps (Teacher, Student, Parent) and shared libraries by addressing
HIGH and MEDIUM priority issues identified in comprehensive expert review.
## Expert Review Results
Implementation assessed at ~90% complete with solid architecture and patterns.
All critical functionality now properly supports edge-to-edge rendering with
landscape support and keyboard handling.
## Changes Made
### HIGH Priority Fixes (Expert Review)
1. **Fixed CanvasScaffold to Support Text Input Screens**
- Added contentWindowInsets parameter with default WindowInsets.navigationBars
- Allows screens to specify IME union for text input or zero insets as needed
- Added comprehensive KDoc with usage examples
- Location: libs/pandautils/src/main/java/com/instructure/pandautils/compose/composables/CanvasScaffold.kt
2. **Fixed Missing IME Insets Request in SpeedGraderCommentsFragment**
- Added ViewCompat.requestApplyInsets() for commentInputContainer
- Ensures IME insets apply immediately when view is attached
- Prevents keyboard appearing before insets are applied
- Location: apps/teacher/src/main/java/com/instructure/teacher/fragments/SpeedGraderCommentsFragment.kt:186-188
3. **Completed Parent App Fragment Coverage**
- Updated SimpleWebViewFragment with toolbar and horizontal insets
- Added applyTopSystemBarInsets() to toolbar in applyTheme()
- Added applyHorizontalSystemBarInsets() to root view in onViewCreated()
- Location: apps/parent/src/main/java/com/instructure/parentapp/features/webview/SimpleWebViewFragment.kt
### MEDIUM Priority Fixes
4. **Fixed Missing Toolbar Insets in AttendanceListFragment**
- Added toolbar.applyTopSystemBarInsets() in setupViews()
- Ensures status bar doesn't overlap toolbar
- Location: apps/teacher/src/main/java/com/instructure/teacher/fragments/AttendanceListFragment.kt:117
5. **Updated 5 Compose Screens with Text Input for IME Support**
- Added WindowInsets.ime.union(WindowInsets.navigationBars) to:
* InboxComposeScreen.kt (subject + body fields)
* RecipientPickerScreen.kt (search field)
* InboxSignatureScreen.kt (signature field)
* CreateUpdateToDoScreen.kt (title/description fields)
* CreateUpdateEventScreen.kt (title/location fields)
- Prevents keyboard from obscuring text input fields
- All locations: libs/pandautils/src/main/java/com/instructure/pandautils/features/*/composables/
6. **Updated 11 Compose Screens with Zero Content Insets**
- Added WindowInsets(0, 0, 0, 0) to read-only/list screens:
* CourseSelectorActivity.kt
* SubmissionListScreen.kt
* SelectContextScreen.kt
* GradePreferencesScreen.kt
* AssignmentListFilterScreen.kt
* CalendarFilterScreen.kt
* ProgressScreen.kt
* ToDoScreen.kt
* EventScreen.kt
* CustomFrequencyScreen.kt
* SpeedGraderCommentLibraryScreen.kt
- Ensures proper edge-to-edge rendering without IME interference
## Architecture Summary
**Hybrid Insets Approach:**
- Horizontal insets → Fragment root views (landscape support)
- Vertical insets → Individual scrollable views
- IME insets → Text input containers (keyboard avoidance)
- Compose contentWindowInsets → Properly configured per screen type
**Patterns Established:**
- View-based fragments: applyHorizontalSystemBarInsets() on root
- Toolbars: applyTopSystemBarInsets() before other setup
- Scrollable content: applyBottomSystemBarInsets() or custom IME handling
- Compose screens: Explicit contentWindowInsets configuration
- FABs: windowInsetsPadding() with systemBars horizontal + bottom
## Files Modified Summary
- 1 Helper class (CanvasScaffold.kt) - Enhanced with parameter
- 3 View-based fragments - Fixed missing insets
- 16 Compose screens - Added contentWindowInsets configuration
- Total: 20 files modified
## Build Verification
✅ Teacher app builds successfully (devDebug)
✅ Student app builds successfully (devDebug)
✅ Parent app builds successfully (devDebug)
## Testing Checklist
Verified:
- [x] All apps compile without errors
- [x] CanvasScaffold parameter properly passed through
- [x] IME insets request added where needed
- [x] Parent app View-based fragments covered
Manual testing recommended:
- [ ] Text input screens - keyboard doesn't obscure inputs
- [ ] Landscape mode - horizontal insets working
- [ ] All bottom navigation screens - content not clipped
- [ ] Dialogs and bottom sheets - proper insets handling

Resolved conflict in SmartSearchPreferencesScreen.kt by keeping CanvasScaffold (from our edge-to-edge branch) instead of plain Scaffold (from master), while preserving the onCancel callback fix from master.

Why is that needed? There is a builtin Modifier that does the same.

I also experienced that Claude doesn't really like to import things. Maybe we could add this to the MD as well. And we should refactor these.

We could make this an extension function, I see a lot of duplication here.
