Phase 2 of Organizr Migration - Front Hall restructure: - Add FrontHallState provider with three modes (dashboard, iframe, settings) - Create QuickLinksPanel widget with categorized links and overflow menus - Add IframeView with platform-aware implementation (web iframe, mobile fallback) - Extract DashboardContent from FrontHallPage - Add QuickLinkSettingsContent placeholder for Phase 4 link editor - Implement QuickLink entity and data layer with Core API datasource - Add default quick links fallback when API unavailable - Update UI_LAYOUT.md with Front Hall panel configurations 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

UI Layout Specification
This document defines the layout structure, responsive behavior, and component constraints for Tatlock UI. It implements the "Rooms of the Estate" metaphor from PHILOSOPHY.md.
Navigation Structure
The UI uses a tabbed room navigation in the header rather than a traditional sidebar. Each "room" represents a distinct usage context, reducing cognitive clutter.
| Room | Purpose | Chat Dock Default |
|---|---|---|
| Front Hall | Dashboard - estate overview, quick access, activity | Expanded |
| Control Room | Infrastructure - containers, stacks, monitoring | Collapsed |
| Parlor | Housekeeping - home automation, devices, scenes | Collapsed |
| Library | Knowledge - docs, notes, bookmarks (future) | Collapsed |
Hidden for now:
- Study - Secretarial tasks (email, calendaring) - future implementation

Panel Taxonomy
All panels share common styling patterns but serve different purposes.
Panel Types
| Panel | Position | Purpose | Width | Content Alignment |
|---|---|---|---|---|
| Header Bar | Top | Room nav, profile | 56px height | Logo in bulge, rest at bottom |
| Nav Panel | Left | Room-level section nav | 280px fixed | Header docked to bottom |
| Filter Panel | Left (inside content) | Data filtering/search | 280px fixed | Header docked to bottom |
| Detail Panel | Right (inside content) | Selected item details | 320-400px | Standard header |
| Chat Dock | Right | AI assistant | 280px-33vw | Standard header |
Panel Header Behavior
All left-side panels (Nav Panel, Filter Panel) dock their header content to the bottom of the header area. This accommodates the logo bulge that overlays into their space.
┌─────────────────────────┐
│ │ ← Logo bulge overlays this space
│ (empty) │
│ │
│ [Icon] Title [Action]│ ← Content docked to bottom (8px margin)
├─────────────────────────┤
│ Panel content... │
Right-side panels (Detail Panel, Chat Dock) use standard vertically-centered headers since the logo bulge doesn't reach them.
Nav Panel Sections
Nav items can be organized into sections. Section headers are conditionally visible - they only appear when multiple sections exist.
Single Section (headers hidden)
When all items belong to one section, no headers are shown:
┌─────────────────────────┐
│ [≡] Sections [···] │ ← Panel header
├─────────────────────────┤
│ ▸ Containers │
│ Networks │
│ Volumes │
│ Images │
│ │
└─────────────────────────┘
Multiple Sections (headers visible)
When items span multiple sections, section headers appear:
┌─────────────────────────┐
│ [≡] Sections [···] │ ← Panel header
├─────────────────────────┤
│ ▌Portainer │ ← Section header (subtle bg, left accent)
│ ▸ Containers │
│ Networks │
│ Volumes │
│ Images │
│ │
│ ▌NPM │ ← Section header
│ Proxy Hosts │
│ Redirections │
│ Streams │
│ │
│ ▌Authentik │ ← Section header
│ Users │
│ Groups │
│ Applications │
│ │
└─────────────────────────┘
Section Header Styling
┌─────────────────────────┐
│▌SECTION NAME │ ← Left accent bar (2px, primary color)
└─────────────────────────┘ ← Background: surfaceContainerHigh
← Text: labelSmall, onSurfaceVariant
← Padding: 8px horizontal, 6px vertical
← All caps, letter-spacing: 0.5
Data Model
/// NavItem model (in nav_panel.dart)
class NavItem {
final String id;
final String label;
final IconData icon;
final String? section; // null = ungrouped
}
// Section headers auto-generate from unique section values
// Visibility: items.map((i) => i.section).toSet().length > 1
Route Configuration Driven
Sections are defined in the feature's route configuration, not the widget:
/// In lib/features/control_room/router.dart
enum ControlRoomNav {
// Portainer section
containers('containers', 'Containers', Icons.dns, 'Portainer'),
networks('networks', 'Networks', Icons.hub, 'Portainer'),
volumes('volumes', 'Volumes', Icons.storage, 'Portainer'),
images('images', 'Images', Icons.photo_library, 'Portainer'),
// NPM section (future)
proxyHosts('proxy-hosts', 'Proxy Hosts', Icons.public, 'NPM'),
redirections('redirections', 'Redirections', Icons.alt_route, 'NPM'),
// Authentik section (future)
users('users', 'Users', Icons.people, 'Authentik'),
groups('groups', 'Groups', Icons.group_work, 'Authentik');
const ControlRoomNav(this.id, this.label, this.icon, this.section);
final String id;
final String label;
final IconData icon;
final String section;
NavItem toNavItem() => NavItem(
id: id,
label: label,
icon: icon,
section: section,
);
}
The NavPanel widget receives items and auto-generates section headers based on unique section values in the list. No section logic lives in the widget - it just renders what the route config provides.
Panel Configurations by Room
Front Hall
Front Hall uses a three-mode content system with a persistent QuickLinks panel:
| Mode | QuickLinks Panel | Content Area |
|---|---|---|
| Dashboard | Normal navigation | Dashboard widgets (stats, weather) |
| Iframe | Normal navigation | Embedded iframe content |
| Settings | Edit mode (back button, add new, overflow menus) | QuickLinkPage (EntityPageScaffold) |

Settings mode panel behavior:
- Back button in header (exits settings mode → dashboard)
- "+ Add New Link" button at top
- Each item has overflow menu (Edit, Delete, Move Up/Down)
- Clicking item selects it for editing in content area
- Uses EntityPageScaffold pattern (no modals)

Grid Specifications
Stat Cards
grid-template-columns: repeat(auto-fit, minmax(180px, 1fr));
gap: 1rem;
| Viewport Width | Cards per Row |
|---|---|
| >= 900px | 4 |
| >= 720px | 3 |
| >= 540px | 2 |
| < 540px | 1 |
Service Cards
grid-template-columns: repeat(auto-fill, minmax(120px, 1fr));
gap: 0.75rem;
Reflows naturally based on available width.
Chat Dock Behavior
The Tatlock chat assistant is omnipresent - accessible from any room.
| State | Width | Trigger |
|---|---|---|
| Expanded | intrinsic (min 280px, max 33vw) | Default on Front Hall, click icon elsewhere |
| Collapsed | 48px (icon rail) | Default on other rooms, viewport < 1200px |
| Overlay | 90vw or 400px max | Expanded on medium viewports |
| Bottom Sheet | 100vw, 60vh max | Mobile viewports |
| Fullscreen | 100vw, 100vh | User-triggered overlay (future) |
Persistence: Conversation state persists across room navigation.
Future: Fullscreen mode provides an immersive chat experience as a modal overlay, independent of the current room.
Flutter Implementation Notes
Panel Widget Library
All panels are built from shared components in lib/shared/layouts/widgets/:
| Widget | File | Purpose |
|---|---|---|
PanelContainer |
panel_container.dart |
Base container for all panels |
PanelHeader |
panel_header.dart |
Configurable header (bottom-docked or centered) |
NavPanel |
nav_panel.dart |
Left-side room navigation |
FilterPanel |
filter_panel.dart |
Left-side data filtering |
DetailPanel |
detail_panel.dart |
Right-side item details |
ChatDock |
chat_dock.dart |
Right-side AI assistant |
PanelHeader Configuration
/// Panel header with configurable content alignment.
class PanelHeader extends StatelessWidget {
const PanelHeader({
required this.title,
required this.icon,
this.actions,
this.dockToBottom = false, // true for left-side panels
});
}
Left-side panels (Nav, Filter) use dockToBottom: true to accommodate the logo bulge:
- Header height: 56px (matches app header)
- Content aligned to bottom with 8px margin
- Empty space at top allows logo bulge overlay
Right-side panels (Detail, Chat) use dockToBottom: false:
- Standard vertically-centered content
- No accommodation needed for logo bulge
Recommended Widgets
| Concept | Flutter Widget |
|---|---|
| Breakpoint detection | LayoutBuilder, MediaQuery |
| Main layout | Row with Expanded and SizedBox |
| Collapsible dock | AnimatedContainer or AnimatedSize |
| Grid layouts | GridView.builder with SliverGridDelegateWithMaxCrossAxisExtent |
| Drawer fallback | Scaffold.drawer or custom Drawer |
| Bottom sheet chat | showModalBottomSheet or DraggableScrollableSheet |
Breakpoint Constants
abstract class Breakpoints {
static const double mobile = 600;

static const double medium = 1200;
}
Panel Width Constants

}
Layout Builder Pattern
LayoutBuilder(
builder: (context, constraints) {
if (constraints.maxWidth >= Breakpoints.medium) {
return WideLayout(...);
} else if (constraints.maxWidth >= Breakpoints.compact) {
return MediumLayout(...);
} else {
