 WHAT TO PLACE FIELDS ON (only these):
 - Visible blank underlines: ____________ (a horizontal line with nothing on it)
 - Labeled blank lines: "Name: ______", "Address: ______", "Price: $______"
-- Signature lines labeled "(Seller's Signature)", "(Buyer's Signature)", "(Agent)", etc.
+- SIGNATURE BLOCK PATTERN (common in real estate docs): a blank underline on one line, with a label like "(Seller's Signature)", "(Date)", "(Address/Phone)" printed BELOW it on the next line. Place the field ON the blank underline line, not on the label line.
 - Date underlines labeled "(Date)" or similar
 - Initials boxes: small "[ ]" or "____" next to "Initials" labels, usually at page bottom margins
 
 WHAT NOT TO PLACE FIELDS ON — STRICT:
-- ANY paragraph body text, even if it contains an address, name, or value inline
-- Document title, headings, section numbers
-- Printed values that are already filled in (e.g. a pre-printed address in the document body)
-- Descriptive or instructional text
-- If the text is part of a sentence or clause, do NOT place a field on it
+- ANY paragraph body text or sentence, even if it contains a name or address inline
+- Document title, headings, section numbers, legal boilerplate paragraphs
+- The label text itself — e.g. "(Seller's Signature)" is a label, NOT a blank; place the field on the line ABOVE it
+- Printed values already filled in
 
 FIELD TYPES:
 - "client-signature" → buyer or seller/client signature lines
