A stricter rule for how pages are styled.
Browsers can now refuse inline styling on LFW.com entirely. Every value that used to be written onto an individual element is a named style or a stylesheet of its own, which closes the last permissive rule in the site's content security policy.
The site had 9,807 of these attributes, almost all of them repeated menu and code-sample values. A build check now fails the release if one returns, so the rule cannot quietly lapse. Pages look and load the same; the saving was a few hundred compressed bytes, and the reason to do it was the policy.
