Stack Auth Dashboard Design Guide

This guide defines the source of truth for dashboard UI design and implementation. It is intentionally written for both humans and AI agents.

If this guide conflicts with older examples in the codebase, follow this guide.

---

1) Core Principle (Non-Negotiable)

Always prefer components from apps/dashboard/src/components/design-components.

• Do not build new ad-hoc visual primitives (for example custom GlassCard, custom ChartCard, custom badge pills, custom pill toggles, custom list rows) if a design-components component exists.
• If the desired UI can be achieved by tweaking/customizing/extending a design-components component, do that instead of creating a page-local alternative.
• In all cases, default to design-components first; only use a non-design-components approach when there is absolutely no viable way to achieve the result with design-components.
• Use @/components/ui/* primitives only when no design-components equivalent exists, or when the design-components component intentionally wraps the primitive.
• Match existing design-components behavior:
  • hover-exit transitions (transition-* duration-150 hover:transition-none)
  • glassmorphic surfaces where appropriate
  • semantic variants for alerts/badges
  • async-safe click handlers via design-components primitives

---

2) Fast Decision Tree

Use this when implementing a new dashboard UI quickly:

1. Need a section container/card?
   • Use DesignCard.
   • For chart-heavy analytics surfaces (especially Recharts tooltips/overflow), use DesignAnalyticsCard.
2. Need user-facing status/info/warning/error message?
   • Use DesignAlert.
3. Need small semantic label (sent, failed, queued, active)?
   • Use DesignBadge.
4. Need user action button, especially async?
   • Use DesignButton.
5. Need text input/selectors in design-components surfaces?
   • Use DesignInput and DesignSelectorDropdown.
6. Need a segmented/pill switcher?
   • Use DesignPillToggle.
7. Need category tabs with count badges?
   • Use DesignCategoryTabs.
8. Need row/list item with action buttons/menu?
   • Use DesignListItemRow (or DesignUserList for user rows).
9. Need settings/property grid editor?
   • Use DesignEditableGrid.
10. Need interactive / sortable / searchable data table?

• Use DataGrid + useDataSource + createDefaultDataGridState from @stackframe/dashboard-ui-components.

11. Need dropdown action/selector/toggle menu?

• Use DesignMenu.

---

3) Allowed Base UI Usage

@/components/ui/* can still be used for primitives that do not currently have a design-components equivalent:

• dialogs/sheets/popovers (ActionDialog, FormDialog, Sheet, etc.)
• complex layout containers where design-components does not provide one
• highly specialized editor internals

When using a primitive directly:

• keep visual style compatible with design-components surfaces
• do not duplicate a design-components component API locally
• consider creating/extending a design-components component instead of repeating local patterns

---

3.1) Best Practices (Always Apply)

• Build with design-components primitives first, then add minimal page-level styling.
• Keep components composable: pass data/config via props instead of hardcoding display logic.
• Favor semantic APIs (variant, color, gradient) over raw class-heavy style forks.
• Use accessible defaults:
  • clear labels for icon-only controls
  • keyboard focus visibility (focus-visible:*)
  • semantic roles where applicable
• Keep behavior deterministic:
  • one visual language per screen
  • one status-color mapping across all routes
  • one interaction pattern per control type

---

3.2) Color System (Light + Dark Theme)

Use semantic tokens and design-components variants first. Avoid ad-hoc hardcoded colors unless there is a documented semantic reason.

Theme token usage priority

1. Use component variants (DesignAlert, DesignBadge, DesignCard gradient, tab/toggle gradients).
2. Use semantic Tailwind tokens (bg-background, text-foreground, text-muted-foreground, border-border).
3. Use opacity layers for subtle surfaces (for example bg-foreground/[0.03]).

Surface and text rules

• Primary surfaces: bg-background + subtle ring/border.
• Secondary/muted surfaces: low-opacity foreground overlays.
• Primary text: text-foreground.
• Secondary text: text-muted-foreground.
• Never use pure black/white hardcoded utility values for app UI text/surfaces.

Semantic state colors

• Success: green/emerald (DesignAlert variant="success", DesignBadge color="green")
• Error: red (DesignAlert variant="error", DesignBadge color="red")
• Warning: orange/amber (DesignAlert variant="warning", DesignBadge color="orange")
• Info: blue/cyan (DesignAlert variant="info", DesignBadge color="blue" or "cyan")

Light vs dark guidance

• Ensure every custom color choice has dark-mode readability.
• In dark mode, reduce high-contrast fills and rely on low-opacity tints + rings.
• Keep contrast high for text and medium for non-critical chrome.

---

3.3) Typography System

Keep typography concise and consistent. Prefer existing design-components/header patterns.

Recommended scale and usage

• Page title: text-xl sm:text-2xl font-semibold tracking-tight
• Section heading: text-xs font-semibold uppercase tracking-wider
• Body/default control text: text-sm
• Secondary metadata: text-xs text-muted-foreground
• Micro labels/badges: text-[10px] to text-[11px]

Typography rules

• Use uppercase tracking only for section labels and compact metadata headings.
• Avoid introducing new arbitrary font sizes when an existing size serves the purpose.
• Keep line-length short in cards and alerts for scanability.
• For numeric/stat values, use tabular numerals where needed.

---

3.4) Spacing and Layout Guidelines

Use a compact, repeatable spacing rhythm.

Spacing rhythm

• gap-1 (4px): tight icon/text coupling
• gap-2 (8px): compact control spacing
• gap-3 (12px): standard row spacing
• gap-4 (16px): section-internal spacing
• gap-5 (20px): larger section grouping

Padding rhythm

• p-2 / px-3 py-2: compact controls
• p-3: standard compact blocks
• p-4 to p-5: card content/major sections

Layout rules

• Use rounded-2xl for major containers/cards.
• Use rounded-xl for controls (inputs, toggles, small cards).
• Preserve visual hierarchy:
  • page spacing > section spacing > control spacing
• Avoid mixing unrelated spacing scales inside a single component.

---

3.5) Animation and Micro-Interactions

Motion should feel immediate, subtle, and informative.

Core motion rules

• No hover-enter delay transitions.
• Use hover-exit transitions: transition-* duration-150 hover:transition-none.
• Keep interaction transitions short and subtle.
• Do not use large animated movement in dense admin surfaces.

Duration guidance

• 50ms-100ms: very small icon feedback
• 150ms: standard hover/focus/press recovery
• 200ms-300ms: layout/state transitions (panel collapse, sheet-like reveals)
• >300ms: only ambient/non-critical effects

Micro-interaction patterns

• Hover:
  • text brightens slightly
  • ring/shadow intensifies subtly
• Press:
  • instant feedback (no delayed press animation)
• Focus:
  • visible focus-visible ring on all interactive elements
• Loading:
  • use design-components built-in loading states (DesignButton, tabs/toggles with async)
  • never freeze the UI without feedback

Motion accessibility

• Respect prefers-reduced-motion for non-essential effects.
• Keep micro-interactions understandable without relying on animation alone.

---

3.6) Best-Practice Checklist (Visual + UX)

• Uses design-components primitives before custom wrappers.
• Uses semantic variants/colors instead of custom status styles.
• Works in both light and dark themes with readable contrast.
• Uses approved typography scale and hierarchy.
• Uses consistent spacing rhythm (gap-2/3/4, p-3/4/5).
• Uses snappy hover-exit transitions and clear focus rings.
• Provides clear loading/disabled/empty/error states.

---

4) Component-by-Component Contract

This section is prescriptive: use these components with these props for these scenarios.

4.1 DesignCard

File: apps/dashboard/src/components/design-components/card.tsx

Use for:

• page sections
• grouped controls
• analytics panels
• list containers
• glassmorphic blocks used in email/project pages

Props you should use most:

• title, icon, optional subtitle for section headers
• gradient: "blue" | "cyan" | "purple" | "green" | "orange" | "default"
• glassmorphic (optional explicit override)
• contentClassName for content spacing overrides

Important behavior:

• If title is provided, icon is required by type.
• Layout is auto-derived:
  • title + subtitle -> full header
  • title only -> compact header
  • no title -> body-only card
• useGlassmorphicDefault() makes nested components default to glassmorphic behavior.

Default recommendation:

• for dashboard sections, use glassmorphic style (either explicit or via nesting context)
• use gradient="default" unless there is semantic reason for colored tint

4.1.1 DesignAnalyticsCard (and chart helpers)

File: apps/dashboard/src/components/design-components/analytics-card.tsx

Use for:

• chart-heavy analytics shells on overview and metrics surfaces
• cards where chart tooltips need to escape clipping/stacking issues
• previously duplicated glass analytics wrappers (ChartCard, GlassCard clones)

Exports:

• DesignAnalyticsCard
• DesignAnalyticsCardHeader
• DesignChartLegend
• useInfiniteListWindow
• DesignInfiniteScrollList

DesignAnalyticsCard props:

• gradient: "blue" | "cyan" | "purple" | "green" | "orange" | "slate"
• className

Rules:

• prefer DesignAnalyticsCard over local chart wrappers for overview/analytics cards
• keep chart implementation local (Recharts config, data transforms), but keep shell/legend/list plumbing shared
• use DesignChartLegend instead of hand-rolled dot/label legend rows when layout matches
• use useInfiniteListWindow for incremental scrolling lists in analytics/list tabs

4.2 DesignAlert

File: apps/dashboard/src/components/design-components/alert.tsx

Use for:

• save success/failure
• warning states (for example SMTP/provider configuration warnings)
• informational notices

Props:

• variant: "default" | "success" | "error" | "warning" | "info"
• title
• description
• glassmorphic when rendered on glass surfaces

Rules:

• use semantic variant instead of custom alert class combinations
• keep title short and actionable
• put longer explanation in description

4.3 DesignBadge

File: apps/dashboard/src/components/design-components/badge.tsx

Use for:

• status chips (sent, failed, queued, draft, active)
• small semantic labels in headers and lists

Props:

• label
• color: "blue" | "cyan" | "purple" | "green" | "orange" | "red"
• icon (optional)
• size: "sm" | "md"
• contentMode: "both" | "text" | "icon"

Rules:

• choose color by meaning, not preference
• use contentMode="icon" only when icon is provided
• for icon-only badges, accessibility is already handled via aria-label

4.4 DesignButton

File: apps/dashboard/src/components/design-components/button.tsx

Use for:

• all primary/secondary actions in dashboard surfaces
• async submit/save/delete actions

Props:

• variant: "default" | "destructive" | "outline" | "secondary" | "ghost" | "link" | "plain"
• size: "default" | "sm" | "lg" | "icon"
• onClick (can be async)
• loading (optional controlled mode)
• loadingStyle: "spinner" | "disabled"
• asChild if composition with links/triggers is needed

Rules:

• prefer DesignButton over base Button for async behavior and consistent loading semantics
• do not hand-roll loading spinners for standard button actions

4.5 DesignInput

File: apps/dashboard/src/components/design-components/input.tsx

Use for:

• text fields inside design-components surfaces
• compact filter fields and inline settings inputs

Props:

• size: "sm" | "md" | "lg"
• prefixItem for fixed prefix UI
• leadingIcon for icon-leading input
• regular input props (placeholder, value, onChange, disabled, etc.)

Rules:

• use prefixItem for prefixed values (domains/paths/currency symbols)
• use leadingIcon for search or query fields

4.6 DesignSelectorDropdown

File: apps/dashboard/src/components/design-components/select.tsx

Use for:

• standard single-select dropdowns in dashboard settings and filters

Props:

• value
• onValueChange
• options: { value, label, disabled? }[]
• placeholder
• size: "sm" | "md" | "lg"
• disabled

Rules:

• prefer this instead of raw Select in feature pages unless custom behavior is required

4.7 DesignPillToggle

File: apps/dashboard/src/components/design-components/pill-toggle.tsx

Use for:

• segmented controls
• viewport switches
• compact mode switches

Props:

• options: { id, label, icon? }[]
• selected
• onSelect
• size: "sm" | "md" | "lg"
• gradient
• showLabels (set false for icon-only controls)
• glassmorphic

Rules:

• do not create custom inline pill toggle components if this fits
• use showLabels={false} only with clear icons and tooltip-friendly labels

4.8 DesignCategoryTabs

File: apps/dashboard/src/components/design-components/tabs.tsx

Use for:

• top-level category switching with optional count badges

Props:

• categories: { id, label, count?, badgeCount? }[]
• selectedCategory
• onSelect
• showBadge
• size: "sm" | "md"
• gradient
• glassmorphic

Rules:

• use for category-level navigation, not micro toggles
• if there are no category counts and control is small, DesignPillToggle may be better

4.9 DesignMenu

File: apps/dashboard/src/components/design-components/menu.tsx

Use for:

• standard row/card action menus
• selector menu (radio group)
• toggles menu (checkbox items)

Variants and required props:

• variant="actions" with items
• variant="selector" with options, value, onValueChange
• variant="toggles" with options, onToggleChange

Common shared props:

• trigger: "button" | "icon"
• triggerLabel
• triggerIcon
• align
• label
• withIcons

Rules:

• prefer this over local DropdownMenu wrappers for common action menus

4.10 DesignListItemRow and DesignUserList

File: apps/dashboard/src/components/design-components/list.tsx

Use for:

• structured list rows with optional per-row actions
• user activity/user list rows

DesignListItemRow props:

• title, optional subtitle
• icon
• size: "sm" | "lg"
• buttons (direct actions or menu actions)
• onClick

DesignUserList props:

• users: { name, email, time, color? }[]
• onUserClick
• showAvatar
• gradient: "blue-purple" | "cyan-blue" | "none"

Rules:

• use size="sm" for dense lists
• use size="lg" for card-like list entries
• replace custom row/card list items with this unless layout is truly unique

4.11 DesignEditableGrid

File: apps/dashboard/src/components/design-components/editable-grid.tsx

Use for:

• key/value settings editors
• mixed-type setting controls
• deferred save/discard patterns

Props:

• items (typed union: text, boolean, dropdown, custom-dropdown, custom-button, custom)
• columns: 1 | 2
• deferredSave, hasChanges, onSave, onDiscard
• externalModifiedKeys

Rules:

• prefer this for config forms that are row-based and editable inline
• use deferred save mode when many fields should be committed together

4.12 DataGrid + useDataSource + createDefaultDataGridState

Package: @stackframe/dashboard-ui-components

Use for:

• interactive, sortable, searchable data tables
• any table with more than ~20 rows or that needs pagination, column visibility, quick search, or CSV export

Canonical pattern:

import { DataGrid, useDataSource, createDefaultDataGridState, type DataGridColumnDef } from "@stackframe/dashboard-ui-components";

const columns: DataGridColumnDef<MyRow>[] = [
  { id: "name", header: "Name", accessor: "name", width: 200, type: "string" },
  { id: "status", header: "Status", accessor: "status", width: 120, type: "singleSelect",
    valueOptions: [{ value: "active", label: "Active" }, { value: "inactive", label: "Inactive" }],
    renderCell: ({ value }) => <DesignBadge label={String(value)} color={value === "active" ? "green" : "red"} size="sm" /> },
];

const [gridState, setGridState] = useState(() => createDefaultDataGridState(columns));
const gridData = useDataSource({
  data: myRows,
  columns,
  getRowId: (row) => row.id,
  sorting: gridState.sorting,
  quickSearch: gridState.quickSearch,
  pagination: gridState.pagination,
  paginationMode: "client",
});

<DataGrid
  columns={columns}
  rows={gridData.rows}
  getRowId={(row) => row.id}
  totalRowCount={gridData.totalRowCount}
  isLoading={gridData.isLoading}
  state={gridState}
  onChange={setGridState}
  toolbar={false}       // set to false to hide; omit for default toolbar
  onRowClick={(row) => handleClick(row)}
  maxHeight={400}
/>

Key props:

• columns (DataGridColumnDef[]): column definitions with id, header, accessor, type, optional renderCell, optional cellOverflow
• rows (TRow[]): always gridData.rows from useDataSource, NEVER your raw array
• getRowId ((row) => RowId): unique row identifier (RowId is string)
• state / onChange: fully controlled grid state (sorting, pagination, search, visibility)
• totalRowCount: total rows for pagination display
• toolbar: false to hide, omit for default, or render function for custom
• onRowClick: optional row click handler
• maxHeight: max pixel height before scrolling
• rowHeight: number (default 44) for fixed height, or "auto" for dynamic row measurement
• estimatedRowHeight: estimated row height for the virtualizer when rowHeight="auto" (default 44)

Cell overflow:

• cellOverflow: "truncate" (default): single-line with text-overflow ellipsis
• cellOverflow: "wrap": content wraps naturally; rows grow when rowHeight="auto"
• Use cellOverflow: "wrap" for badge lists, permission chips, multi-line text
• Use default truncate for UUIDs, emails, dates, single-line text

const columns: DataGridColumnDef<MyRow>[] = [
  { id: "userId", header: "User ID", width: 130 },                            // truncates (default)
  { id: "auth", header: "Auth methods", width: 150, cellOverflow: "wrap",     // badges wrap, row grows
    renderCell: ({ row }) => (
      <div className="flex flex-wrap gap-1">
        {row.authTypes.map((t) => <Badge key={t}>{t}</Badge>)}
      </div>
    ),
  },
];

<DataGrid columns={columns} rowHeight="auto" estimatedRowHeight={48} ... />

Rules:

• always initialize state with createDefaultDataGridState(columns) — never build the state object by hand
• always use useDataSource to process data — the grid does not sort/filter/paginate on its own
• columns must be stable across renders (define outside component or wrap in useMemo)
• renderCell must be a pure function — no React hooks inside it
• read the full JSDoc on the DataGrid component for iron rules and advanced usage

4.13 CursorBlastEffect

File: apps/dashboard/src/components/design-components/cursor-blast-effect.tsx

Use for:

• optional high-feedback interactions (playground/internal prototyping)

Props:

• blastLifetimeMs
• maxActiveBlasts
• rageClickThreshold
• rageClickWindowMs
• rageClickRadiusPx
• containerRef

Rules:

• keep as optional enhancement, not required UX
• avoid distracting overuse in production-critical flows

5) Route-Specific Guidance (Project + Email Surfaces)

Reference surfaces:

• apps/dashboard/src/app/(main)/(protected)/projects/[projectId]
• apps/dashboard/src/app/(main)/(protected)/projects/[projectId]/emails
• apps/dashboard/src/app/(main)/(protected)/projects/[projectId]/email-drafts
• apps/dashboard/src/app/(main)/(protected)/projects/[projectId]/email-outbox
• apps/dashboard/src/app/(main)/(protected)/projects/[projectId]/email-templates
• apps/dashboard/src/app/(main)/(protected)/projects/[projectId]/email-themes

Current pattern in these pages often uses custom card/header/pill components. New and refactored code should standardize to design-components primitives as follows.

5.0 /projects/[projectId]/(overview) analytics surfaces

Use:

• chart/list shells: DesignAnalyticsCard
• compact chart headers: DesignAnalyticsCardHeader
• stacked chart legends: DesignChartLegend
• incremental list rendering: useInfiniteListWindow (or DesignInfiniteScrollList where it fits)

Avoid:

• page-local ChartCard wrappers
• duplicated IntersectionObserver list window logic per card

5.1 /projects/[projectId]/emails

Use:

• section containers: DesignCard (title, icon, optional subtitle, gradient)
• alerts: DesignAlert (variant by state)
• status chips: DesignBadge (green for sent, red for failed)
• actions: DesignButton
• table: DataGrid + useDataSource + createDefaultDataGridState

Avoid:

• custom GlassCard
• custom status-badge component
• raw Alert unless special composition is required

5.2 /projects/[projectId]/email-drafts (list)

Use:

• list container: DesignCard
• row items: DesignListItemRow (size="lg" for card rows or size="sm" for dense list)
• row menus: DesignMenu with variant="actions"
• empty state action: DesignButton

Avoid:

• custom DraftCard for standard list row behavior

5.3 /projects/[projectId]/email-drafts/[draftId] (editor)

Use:

• status/sync alerts: DesignAlert
• scope/status chips: DesignBadge
• editor side controls: DesignButton, DesignSelectorDropdown, DesignInput as needed

Keep:

• specialized editor layout systems if no design-components equivalent exists

5.4 /projects/[projectId]/email-outbox

Use:

• section cards: DesignCard (preferred for visual consistency with other email screens)
• filters: DesignSelectorDropdown, DesignInput
• status badges: DesignBadge
• action buttons/menus: DesignButton, DesignMenu
• data grid/list table: DataGrid + useDataSource + createDefaultDataGridState

Avoid:

• mixed badge systems (Badge in some places, custom badges elsewhere)

5.5 /projects/[projectId]/email-templates

Use:

• template item containers: DesignCard (gradient per semantic section)
• alerts/warnings: DesignAlert
• actions: DesignButton
• template row action menu: DesignMenu

Avoid:

• inline repeated glass class blocks for each template card

5.6 /projects/[projectId]/email-templates/[templateId]

Use:

• save/error notices: DesignAlert
• top actions: DesignButton
• state tags: DesignBadge where needed

5.7 /projects/[projectId]/email-themes

Use:

• section containers: DesignCard
• viewport/device selector: DesignPillToggle
• status messages: DesignAlert
• theme state badges: DesignBadge
• actions: DesignButton, DesignMenu

Avoid:

• custom ViewportSelector if DesignPillToggle supports the same behavior

5.8 /projects/[projectId]/email-themes/[themeId]

Use:

• state feedback: DesignAlert
• actions: DesignButton
• optional segmented controls: DesignPillToggle

---

6) Semantic Mapping Rules

Use consistent semantic color/variant mapping across all pages:

• Success/completed/sent -> DesignAlert variant="success" and DesignBadge color="green"
• Error/failed -> DesignAlert variant="error" and DesignBadge color="red"
• Warning/attention -> DesignAlert variant="warning" and DesignBadge color="orange"
• Info/neutral updates -> DesignAlert variant="info" and DesignBadge color="blue" or "cyan"

Gradient mapping for cards/tabs/toggles:

• Blue: primary navigation/state
• Cyan: analytics/activity
• Purple: templates/themes or creative tools
• Green: success/completion
• Orange: warnings/caution
• Default: neutral/system sections

---

7) Interaction and Motion Rules

These rules must be preserved in custom styling and overrides:

• no hover-enter delays
• use hover-exit transitions: transition-* duration-150 hover:transition-none
• keep controls snappy and readable
• avoid heavy animation in dense admin workflows

For async actions:

• prefer design-components primitives that already handle async/loading
• do not swallow async errors; use existing alert-aware async utilities through design-components primitives

---

8) AI-Readable Implementation Checklist

Use this checklist before opening a dashboard UI PR:

• Replaced ad-hoc cards with DesignCard where possible.
• Replaced ad-hoc alerts with DesignAlert.
• Replaced ad-hoc badges/status pills with DesignBadge.
• Replaced ad-hoc segmented controls with DesignPillToggle or DesignCategoryTabs.
• Replaced ad-hoc row/list cards with DesignListItemRow or DesignUserList.
• Used DesignButton for async actions.
• Used DesignSelectorDropdown/DesignInput for standard field controls.
• Used DataGrid + useDataSource + createDefaultDataGridState for interactive tables.
• Did not introduce duplicate local wrappers for components already in design-components.
• Kept hover/motion behavior aligned with this guide.

---

9) Quick Snippets (Canonical)

Section Card

<DesignCard
  title="Email Log"
  subtitle="View and manage email sending history"
  icon={Envelope}
  gradient="default"
>
  {/* content */}
</DesignCard>

Semantic Alert

<DesignAlert
  variant="error"
  title="Failed to send email"
  description="Please verify provider configuration and try again."
/>

Status Badge

<DesignBadge
  label="Sent"
  color="green"
  icon={CheckCircle}
  size="sm"
/>

Viewport Toggle

<DesignPillToggle
  options={[
    { id: "desktop", label: "Desktop", icon: Desktop },
    { id: "tablet", label: "Tablet", icon: DeviceTablet },
    { id: "mobile", label: "Mobile", icon: DeviceMobile },
  ]}
  selected={viewport}
  onSelect={setViewport}
  size="sm"
  gradient="default"
/>

Category Tabs

<DesignCategoryTabs
  categories={[
    { id: "all", label: "All", count: 42 },
    { id: "failed", label: "Failed", count: 3 },
  ]}
  selectedCategory={category}
  onSelect={setCategory}
  gradient="blue"
/>

---

10) Anti-Patterns (Do Not Introduce)

• Creating local GlassCard/ChartCard components instead of DesignCard or DesignAnalyticsCard.
• Creating local status pills instead of DesignBadge.
• Creating local segmented/pill selectors instead of DesignPillToggle.
• Using raw Alert/Button in standard dashboard surfaces where DesignAlert/DesignButton should be used.
• Using DesignDataTable or raw DataTable instead of DataGrid + useDataSource + createDefaultDataGridState. DesignDataTable is deprecated; all new and migrated tables use DataGrid.
• Repeating large inline class strings for common design-components patterns.

---

11) Migration Priority for Existing Email Surfaces

When touching existing email/project pages, migrate in this order:

1. Cards/surfaces (DesignCard / DesignAnalyticsCard for chart-heavy shells)
2. Alerts (DesignAlert)
3. Badges (DesignBadge)
4. Toggles/tabs (DesignPillToggle / DesignCategoryTabs)
5. Rows/lists (DesignListItemRow)
6. Buttons/menus (DesignButton / DesignMenu)
7. Tables/forms (DataGrid, DesignInput, DesignSelectorDropdown, DesignEditableGrid)

This order yields the biggest consistency win first.

---

12) Maintenance Rule

Whenever a new reusable visual pattern is introduced in dashboard features:

• add or extend a design-components component first
• then document the component contract and preferred usage here
• avoid introducing permanent page-local UI primitives that duplicate design-components behavior
