The Site pulled pdf.js 3.11.174 from cdnjs with no integrity attribute, and the
policy trusted the whole of cdnjs.cloudflare.com for both script-src and
worker-src. Anything that host served would have executed, and a customer
measuring a PDF sheet depended on it being reachable.
Vendor both files instead of pinning a hash: it removes the dependency rather
than constraining it, and lets the policy name only 'self'. Provenance and
SHA-256 digests are recorded in local/static/vendor/README.md, verified on
download against the SRI digests cdnjs publishes for that release.
cdnjs is now absent from script-src, worker-src and connect-src in both gateway
templates. Workers are 'self' plus blob:, which the Site needs for the worker it
constructs itself.
Verified in a browser against the running stack: pdf.js loads from /vendor/, the
blob worker starts, and a real seven-page PDF parses with no CSP violation. Both
browser suites and the full integration suite pass.
The version is deliberately unchanged. 3.11.174 is old, but its known eval path
is already closed by isEvalSupported:false, and upgrading is an API change that
needs its own testing rather than riding along with this.

Navigation links carried data-modo-cta and opened loose artwork directly, so
every entry point except the price card bypassed "Arquivo por metro". Dropping
a PNG or JPG from the by-metre editor then switched the order to loose artwork
and repriced it, while the same screen advertised PNG/JPG in its drop zone and
marked that path as the cheaper one.
Replace the guessing with a declaration: the product is the choice. #tipoEnvio
shows ready sheet and loose artwork side by side with both prices, in all four
modes, reversible until a file is attached and locked afterwards. sel() no
longer reassigns modo, so a file can never change product or price on its own.
Verify the declaration instead of trusting it. medirFolha returns dpiFolha, and
an image without the pixels to span the film width at DPI_RECUSA is refused as
a sheet, with the numbers shown and one click to send it as loose artwork.
Previously a small image declared as a sheet was billed by the metre.
Scope pintaCaminhos to #caminhos .cam: its global selector was clearing the new
control. Move the checkout status out of #carr, which the success path hides,
so a paid order still confirms itself to the customer.
