(Migrated from github.com)

Parent: #77 (Phase B, capability - lowest priority). Invariants live in the epic.

Drop duplicated item blocks from multi-copy receipts.

Anchors

Item list assembled at ReceiptParser.cs:197-209; de-dupe after items exist.
ParsedItem (ParsedReceipt.cs:15) - Name, Quantity, PriceMinor for
the equality check.

Steps

Detect a repeated block of items (merchant/customer/kitchen copies) and keep
one.
Do not collapse a genuinely repeated order of the same item (two of the same
dish is not a duplicate copy).

Done

New fixture with a duplicated copy.
Existing corpus green - legitimately repeated items preserved.
