Phase 16 Plan 03: FieldPlacer Active Signer Selector and Color Override Summary

What Was Built

Added multi-signer UX to FieldPlacer.tsx (822 → 907 lines):

1. activeSignerEmail state — useState<string | null>(null) initialized via useEffect to signers[0].email on mount; resets if signers prop changes or selected signer removed.

2. handleDragEnd signer auto-assignment — ...(activeSignerEmail ? { signerEmail: activeSignerEmail } : {}) added to newField construction so dragged fields are tagged automatically.

3. renderFields signer color override — signers.find(s => s.email === field.signerEmail)?.color overrides type-based color when the field has a signerEmail. Fields without signerEmail retain existing PALETTE_TOKENS color.

4. Unassigned field validation overlay — isUnassigned flag from unassignedFieldIds.has(field.id) applies border: 2px solid #ef4444 / background: #ef444414 to highlight fields needing signer assignment.

5. Active signer selector UI — Native <select> at height: 32px above field palette. Shows only when !readOnly && signers.length > 0. Colored dot indicator (8×8px circle in signer color). Label: "Active signer:" at 12px/500 weight.

6. DragOverlay ghost — Uses activeSigner.color for the ghost field color when an active signer is selected.
