# Phase 37 — UI Design Contract

> Visual and interaction contract for Admin — Global Item Management. Generated from CONTEXT.md decisions, RESEARCH.md findings, and codebase pattern analysis.

---

## Design System

| Property | Value |
|----------|-------|
| Tool | none — Tailwind CSS v4 utility-first |
| Preset | not applicable |
| Component library | none (custom components) |
| Icon library | LucideIcon from `src/client/lib/iconData` |
| Font | System default (Inter-like sans-serif via browser) |

No `components.json` detected. No shadcn. All styling is plain Tailwind utility classes matching the app's existing light/airy aesthetic.

---

## Spacing Scale

Standard 8-point scale from existing app patterns:

| Token | Value | Usage |
|-------|-------|-------|
| xs | 4px (`gap-1`, `p-1`) | Icon gaps, inline chip gaps |
| sm | 8px (`gap-2`, `p-2`) | Compact table cell padding, tag chips |
| md | 16px (`gap-4`, `p-4`) | Default form field spacing, sidebar padding |
| lg | 24px (`gap-6`, `p-6`) | Section padding, edit page padding |
| xl | 32px (`gap-8`, `p-8`) | Page-level layout gaps |
| 2xl | 48px | Major section breaks (used sparingly) |
| 3xl | 64px | Not used in admin panel |

Exceptions:
- Table row height: `py-3` (12px vertical) + `px-4` (16px horizontal) for dense data rows
- Sidebar nav items: `px-3 py-2` (12px vertical) — matches Phase 36 admin shell

---

## Typography

Matches existing app type scale. No new sizes introduced.

| Role | Size | Weight | Line Height | Tailwind |
|------|------|--------|-------------|---------|
| Body / table cell | 14px | 400 | 1.5 | `text-sm` |
| Label / column header | 12px | 600 | 1.4 | `text-xs font-semibold` |
| Form field label | 14px | 600 | 1.4 | `text-sm font-semibold` |
| Page heading | 18px | 600 | 1.3 | `text-lg font-semibold` |

Weights used: 400 (regular) + 600 (semibold). No medium (500), no bold (700).

---

## Color

60/30/10 rule — matches Phase 36 admin shell exactly:

| Role | Value | Tailwind | Usage |
|------|-------|---------|-------|
| Dominant (60%) | #ffffff | `bg-white` | Page backgrounds, table rows, edit form |
| Secondary (30%) | #f9fafb | `bg-gray-50` | Main content area, input backgrounds |
| Border / divider | #f3f4f6 | `border-gray-100` | Table row dividers, sidebar border |
| Text primary | #111827 | `text-gray-900` | Item names, column data |
| Text secondary | #4b5563 | `text-gray-600` | Labels, form hints |
| Text muted | #9ca3af | `text-gray-400` | Column headers, disabled states |
| Accent (10%) | #2563eb | `text-blue-600`, `bg-blue-50` | Save button, active nav link indicator |
| Destructive | #dc2626 | `bg-red-600 hover:bg-red-700` | Delete button ONLY |

Accent reserved for:
- Save/Update primary button
- Active sidebar nav link highlight (left border or background)

Destructive reserved for:
- Delete button in edit page
- Confirm delete button inside the delete dialog

## Component Inventory

### Admin Items List (`/admin/items`)

**Layout:**
```
┌─────────────────────────────────────────────────┐
│ Heading: "Catalog Items"      [search input]    │
│ Tag filter chips                                 │
│ "1,247 items" count label                        │
├──────┬────────────┬─────┬───────┬───────┬───────┤
│ Brand+Model │ Category │ Wt │ Price │ Tags │ Owners│
├──────┴────────────┴─────┴───────┴───────┴───────┤
│ row row row ... (50 per page)                    │
│ [sentinel div — triggers next page]              │
└─────────────────────────────────────────────────┘
```

**Table element specs:**
- Wrapper: `w-full overflow-hidden rounded-xl border border-gray-100 bg-white`
- `<table>`: `w-full text-sm`
- `<thead>`: `bg-gray-50 border-b border-gray-100`
- Column header cells: `px-4 py-3 text-left text-xs font-semibold text-gray-400 uppercase tracking-wide`
- `<tbody>` rows: `border-b border-gray-50 hover:bg-gray-50 cursor-pointer transition-colors`
- Body cells: `px-4 py-3 text-sm text-gray-700`
- Brand+Model cell: bold brand (`font-medium text-gray-900`) + muted model (`text-gray-500`)

**Tags column:**
- ≤ 2 tags: render as inline chips — `text-xs bg-gray-100 text-gray-500 px-2 py-0.5 rounded-full`
- > 2 tags: render count badge — `text-xs bg-gray-100 text-gray-500 px-2 py-0.5 rounded-full` displaying "+N"

**Owner count column:**
- Numeric, right-aligned, `text-gray-500`
- 0 owners: `text-gray-300`

**Search input:**
- `rounded-lg border border-gray-200 px-3 py-2 text-sm focus:outline-none focus:ring-2 focus:ring-blue-500/20 focus:border-blue-300`
- Placeholder: "Search catalog..."

### Delete Confirmation Dialog

Inline state-driven modal (not UIStore — local `useState`):

```
┌──────────────────────────────────────────────┐
│  Delete {Brand} {Model}?                     │
│                                              │
│  {N} users have this item in their           │
│  collection. This cannot be undone.          │
│                                              │
│              [Cancel]  [Delete]              │
└──────────────────────────────────────────────┘
```

- Modal backdrop: `fixed inset-0 z-50 flex items-center justify-center` + `absolute inset-0 bg-black/30`
- Dialog box: `relative bg-white rounded-xl shadow-lg p-6 max-w-sm mx-4 w-full` (matches ConfirmDialog)
- Heading: `text-lg font-semibold text-gray-900 mb-2`
- Body: `text-sm text-gray-600 mb-6`
- Cancel: `px-4 py-2 text-sm font-medium text-gray-700 bg-gray-100 hover:bg-gray-200 rounded-lg`
- Confirm delete: `px-4 py-2 text-sm font-medium text-white bg-red-600 hover:bg-red-700 rounded-lg`

### Sidebar Items Link (admin.tsx update)

Replace the disabled `<div>` with an active `<Link>`:

```tsx
<Link
  to="/admin/items"
  activeProps={{ className: "bg-gray-100 text-gray-900 font-medium" }}
  inactiveProps={{ className: "text-gray-600 hover:bg-gray-50" }}
  className="flex items-center gap-2 px-3 py-2 rounded-lg text-sm transition-colors"
>
  <LucideIcon name="package" size={16} />
  <span>Items</span>
</Link>
```

Remove the "Soon" badge and `cursor-not-allowed` class.

## Copywriting Contract

| Element | Copy |
|---------|------|
| Page heading (list) | "Catalog Items" |
| Item count label | "{N} items" (e.g. "1,247 items") |
| Search placeholder | "Search catalog..." |
| Empty state heading | "No items found" |
| Empty state body | "Try a different search or clear your filters." |
| Edit page — 0 owners | "Not in any collection" |
| Edit page — 1 owner | "1 user in collection" |
| Edit page — N owners | "{N} users in collection" |
| Save CTA | "Save Changes" |
| Delete CTA (edit page) | "Delete Item" |
| Delete dialog heading | "Delete {Brand} {Model}?" |
| Delete dialog body (0 owners) | "This item is not in any collection. This cannot be undone." |
| Delete dialog body (N owners) | "{N} users have this item in their collection. This cannot be undone." |
| Delete dialog confirm | "Delete" |
| Delete dialog cancel | "Cancel" |
| Back link | "← Items" |
| Loading more (infinite scroll) | "Loading..." |
| All items loaded | "All {N} items loaded" |
| Error state | "Failed to load catalog items. Please try again." |
| Save success | (no toast — form stays; navigation optional) |

---

## States to Handle

| Component | States |
|-----------|--------|
| Items list | Loading (skeleton rows), Loaded, Empty, Error, Loading next page |
| Edit page | Loading (skeleton form), Loaded, Saving, Save success, Save error |
| Delete dialog | Closed, Open, Deleting, Delete error |
| Manufacturer dropdown | Loading manufacturers, Loaded |

**Loading skeleton for table rows:**
```
4-6 rows with `<div className="h-4 bg-gray-100 rounded animate-pulse" />` in each cell
```

**Save/delete pending state:**
- Button `disabled` + `opacity-50`
- No spinner needed — button text stays static
