use of dark mode tools makes our website and docs difficult to use
recently in a usability study a participant was using Dark Reader in Firefox which enables a dark mode, but unfortunately, it made our website and docs difficult to use because a number of things were totally invisible
later on a different community member mentioned they were using chrome dark mode and had a similar experience with components being totally invisible.

as more and more folks enable these dark mode solutions we should figure out if we can make our website/service work with them or if we should be shipping our dark mode

My two cents - it's a lot more effort to ship a custom dark mode. However, if employees are using a locked down browser and are unable to add a dark mode extension, or don't want to add a dark mode extension, being able to toggle between light/dark on a website is a huge usability win.
I've also run into the issue w/Pulumi's registry documents working very poorly with Dark Reader for Chrome, however now that I revisit that page to upload a screenshot, it appears that either a change to the extension or to your site's styling has corrected that particular issue.
You should really just add darkmode to your docs and this problem will go away.
The availability of tools like Firefox Reader View and dark mode browser extensions is not a good excuse to not provide a custom dark mode. Those tools are last-ditch attempts to fix accessibility problems with websites. The lack of a dark mode is an accessibility issue. I spend large portions of my day swapping between a terminal, a code editor, the AWS console, and Pulumi docs. Only one of those doesn't ship a dark mode theme. The blast of photons when I switch to a Pulumi docs tab is a physical discomfort.
Modern desktop environments ship with built-in light/dark theme selection options. Modern web browsers persist these settings down into their rendering engines. Modern stylesheets pay attention to those settings to deliver a consistent user experience regardless of the user's preference.
