<objective>
Surface template text hints as quick-fill suggestions in PreparePanel and verify the complete Phase 20 feature set with human testing.

Purpose: When a document is created from a template, text fields with hints (e.g., "Property Address", "Purchase Price") show those hints as one-click quick-fill chips, saving the agent from remembering what each blank field is for.
Output: Modified DocumentPageClient.tsx (fields state + hint derivation), modified PreparePanel.tsx (hint chip), human verification of the full template-to-document flow.

<!-- Key types and contracts from codebase. -->

From src/app/portal/(protected)/documents/[docId]/_components/DocumentPageClient.tsx:
```typescript
interface DocumentPageClientProps {
  docId: string;
  docStatus: string;
  defaultEmail: string;
  clientName: string;
  agentDownloadUrl?: string | null;
  signedAt?: Date | null;
  clientPropertyAddress?: string | null;
  initialSigners: DocumentSigner[];
  clientContacts?: { name: string; email: string }[];
}

// Existing state:
// selectedFieldId: string | null
// textFillData: Record<string, string>
// aiPlacementKey: number
// signers: DocumentSigner[]
```

From src/app/portal/(protected)/documents/[docId]/_components/PreparePanel.tsx:
```typescript
interface PreparePanelProps {
  docId: string;
  defaultEmail: string;
  clientName: string;
  currentStatus: string;
  agentDownloadUrl?: string | null;
  signedAt?: Date | null;
  clientPropertyAddress?: string | null;
  previewToken: string | null;
  onPreviewTokenChange: (token: string | null) => void;
  textFillData: Record<string, string>;
  selectedFieldId: string | null;
  onQuickFill: (fieldId: string, value: string) => void;
  onAiAutoPlace: () => Promise<void>;
  signers?: DocumentSigner[];
  onSignersChange?: (signers: DocumentSigner[]) => void;
  unassignedFieldIds?: Set<string>;
  onUnassignedFieldIdsChange?: (ids: Set<string>) => void;
}
```

Quick Fill section pattern (PreparePanel lines 313-355):
```typescript
{/* Quick-fill panel — only shown when a text field is selected */}
{selectedFieldId ? (
  <div className="space-y-1.5">
    <p className="text-xs text-gray-400">Click a suggestion to fill the selected field.</p>
    {clientName && ( <button onClick={() => onQuickFill(selectedFieldId, clientName)}>...</button> )}
    {clientPropertyAddress && ( <button onClick={() => onQuickFill(selectedFieldId, clientPropertyAddress)}>...</button> )}
    <button onClick={() => onQuickFill(selectedFieldId, defaultEmail)}>Client Email chip</button>
  </div>
) : (
  <p>Click a text field on the document...</p>
)}
```

  </read_first>
  <action>
**In DocumentPageClient.tsx:**

1. Add import: `import type { SignatureFieldData } from '@/lib/db/schema';` (DocumentSigner is already imported).

2. Add state for fields:
```typescript
const [fields, setFields] = useState<SignatureFieldData[]>([]);
```

3. Add useEffect to fetch fields on mount and when aiPlacementKey changes:
```typescript
useEffect(() => {
  fetch(`/api/documents/${docId}/fields`)
    .then(r => r.json())
    .then((data: SignatureFieldData[]) => setFields(Array.isArray(data) ? data : []))
    .catch(() => {});
}, [docId, aiPlacementKey]);
```

4. Derive the hint for the selected field:
```typescript
const selectedFieldHint = selectedFieldId
  ? fields.find(f => f.id === selectedFieldId)?.hint
  : undefined;
```

5. Pass new prop to PreparePanel:
```typescript
<PreparePanel
  // ... all existing props unchanged ...
  selectedFieldHint={selectedFieldHint}
/>
```

**In PreparePanel.tsx:**

1. Add `selectedFieldHint?: string;` to the `PreparePanelProps` interface (after `onQuickFill`).

2. Destructure it in the function signature: add `selectedFieldHint,` to the destructured props.

3. In the Quick Fill section (inside the `{selectedFieldId ? (` branch), add a new chip AFTER the existing Client Email chip button (before the closing `</div>` of `space-y-1.5`):

```tsx
{selectedFieldHint && (
  <button
    type="button"
    onClick={() => onQuickFill(selectedFieldId, selectedFieldHint)}
    className="w-full text-left px-3 py-2 text-sm border rounded bg-white hover:bg-blue-50 hover:border-blue-300 transition-colors"
  >
    <span className="text-xs text-gray-400 block">Template Hint</span>
    <span className="truncate block">{selectedFieldHint}</span>
  </button>
)}
```

This follows the exact same markup pattern as the existing Client Name / Property Address / Client Email chips. The prop is optional with no default — existing callers (DocumentPageClient without template-sourced documents) simply don't pass it, and `undefined` means no chip renders.

  <name>Task 2: Human verification of full template-to-document flow</name>
  <what-built>
    Complete "Start from template" feature:
    - My Templates tab in Add Document modal (Plan 01)
    - Template apply with fresh field UUIDs and role mapping (Plan 01)
    - Text hint quick-fill chips in PreparePanel (Plan 02 Task 1)
    - Templates nav + list page (Phase 19, already live)
  </what-built>
  <how-to-verify>
    Prerequisites: At least one saved template with fields and text hints must exist (created in Phase 19 testing).

    1. Navigate to /portal/templates — verify the list page shows saved templates with form name, field count, and updated date (TMPL-16)
    2. Verify "Templates" appears in the portal top nav (TMPL-15)
    3. Go to a client profile page → click "Add Document"
    4. Verify the modal shows two tabs: "Forms Library" and "My Templates" (TMPL-10)
    5. Click "My Templates" tab → verify saved templates appear with name, form name, and field count
    6. Select a template → verify the document name auto-fills with the template name
    7. Click "Add Document" → verify the document is created and you're returned to the client page
    8. Open the newly created document → verify fields are pre-loaded at the correct positions on the PDF (TMPL-11)
    9. In PreparePanel, click a text field that has a hint → verify a "Template Hint" chip appears in the Quick Fill section alongside Client Name/Address/Email (TMPL-13)
    10. Click the hint chip → verify the field is filled with the hint text
    11. Click the "Forms Library" tab back in a new Add Document modal → verify the existing form library still works exactly as before (D-04)
    12. (TMPL-14 — snapshot independence): Go to /portal/templates → edit the template (change a field position) → go back to the document created in step 7 → verify the document's fields are unchanged (still at original positions)

1. `cd teressa-copeland-homes && npx tsc --noEmit` — zero type errors
2. `cd teressa-copeland-homes && npm run build` — production build succeeds
3. Human verification confirms all 12 steps pass
4. TMPL-10 through TMPL-16 all satisfied (TMPL-14/15/16 by design or Phase 19)
</verification>

<success_criteria>
- Template Hint chip appears in Quick Fill when a text field with a hint is selected
- Chip click fills the field (same behavior as existing quick-fill chips)
- Fields without hints show no extra chip
- Human confirms full template-to-document flow works end-to-end
- All 7 TMPL requirements (TMPL-10 through TMPL-16) are satisfied
