This is ready to merge. I found no correctness problems, and the code does what the description says.
Contract compatibility. docs/api.md counts a change to an existing field's meaning as a breaking change. The field that comes closest here is unit_cents: it used to always equal the menu price and now includes the size adjustment. Older clients don't send size, though, so they always get medium and a 0¢ adjustment, and every request they can make returns the same unit_cents, line_cents and totals as before. So I read this as an added optional field plus an added response field, which the contract allows. I checked the docs example by hand (900 − 90 + 71 = 881), and the new examples work out too: 571, 544, 1387 and 1028 all match the round-half-up tax formula in quoteOrder.
Validation and errors. The unknown-size error is a plain fmt.Errorf, and main.go sends every error except ErrEmptyOrder to 422, so the documented status holds. TestOrdersEndpointUnknownSize checks that end to end. Sizes are case-sensitive, as the docs say: "Large" returns 422.
Tests. TestQuoteOrder only compares totals. TestQuotedLineSize fills that gap by comparing whole QuotedLine structs, so it checks Size, UnitCents and LineCents on each line, including a line that defaults to medium. The endpoint test also confirms that size appears in the response JSON.
Front end. The data-id moved from the input to the row div, and nothing else in the repo reads it. The select can only send one of the three valid sizes. capitalize(l.size) is safe because the server always sets size.
Why I recommend approval: it's a small change to the demo app, every pricing path it adds has tests, and clients that don't send size get exactly the same responses as before.
Verdict: ready
