Phase 16 Plan 02: PreparePanel Signer List UI Summary

What Was Built

Modified PreparePanel.tsx (+104 lines) and prepare/route.ts (+5 lines):

PreparePanel.tsx:

• SIGNER_COLORS = ['#6366f1', '#f43f5e', '#10b981', '#f59e0b'] — auto-assigned by index
• Props destructured: signers, onSignersChange, onUnassignedFieldIdsChange
• handleAddSigner — validates email format + duplicate, assigns next color from palette, calls onSignersChange
• handleRemoveSigner — filters signer from list, clears unassignedFieldIds
• Signer list UI section (Draft-only, inserted above Prepare and Send):
  • Email <input> + "Add Signer" <button> (height 32px)
  • Per-signer row: 8×8px colored dot (w-2 h-2 rounded-full) + email text + × remove button with aria-label="Remove signer {email}" (32×32px touch target)
  • Empty state: "No signers added yet."
  • Duplicate email warning: "That email is already in the signer list."
• handlePrepare extended: fetches current fields via /api/documents/{id}/fields, checks unassigned isClientVisibleField fields, sets unassignedFieldIds and shows inline error if found
• signers included in prepare POST body so documents.signers is persisted before send route reads it

prepare/route.ts:

• Body type extended with signers?: DocumentSigner[]
• DB update spreads { signers: body.signers } when provided
