The price depends on the grade, which the browser worked out and the API took on trust. Before a cart is approved at checkout the API now recomputes it from the uploaded files by the Site's own rules: the pixel size in a PNG, JPG or WebP header across the printed width (rotation included), and the area-weighted DPI of the images placed in a PDF of up to 150 MB, 300 for vectors. Sheets take the worst grade, artworks the average. A claim more than 2 points above the file's grade, or a discount on a file the server cannot grade, waits for an operator, with the reason on the Kanban.

"""Quote approval: automatic at checkout, by an operator for the exceptions.
|
|
|
|
A quote the customer can pay is priced here from the server's own ladders,
|
|
whether an operator approved it on the Kanban or the Site approved it the
|
|
moment it was created. The Site is a shop: a customer who can price the order
|
|
should be able to pay for it straight away, at any hour, so only orders a
|
|
person must look at before charging wait for the Kanban (review_reason).
|
|
|
|
The grade (and so the discount) is worked out in the customer's browser and
|
|
checked against the files before an automatic approval (app/grade_check.py);
|
|
a grade the files do not support waits for review. The layout is still the
|
|
browser's (roadmap 3.9): the API checks its geometry. Operators see every
|
|
order's grade and artwork at Arte recebida.
