Fixes:
- There is no easy way for a user to reset their day/night preference back to automatic (currently, they must use their web browser to clear the local storage data for the site)
- When changing the theme variation is disabled by admin (by setting `day_night` to `false` in `params.toml`), the operating system's day/night preference is still applied
- If the admin removes the option to change the theme variation, the preference for a user who already visited the site is still read from the localstorage and applied. For example, this could result in the user seeing a theme variation with poor contrast that was not intended to be shown as the site's theme was optimized for the other variation.
Fix#1385Fix#1526Fix#1534
The proportion of image data in the typical payload of a website can be significant. Lazy loading is a solution that lowers initial page payload and load time, without removing content. Non-critical resources are instead loaded at the moment that they are needed.
Also, load MathJax async in head if required, rather than at end of body.
