Why it exists
Most optimization plugins speed a site up until the day they break it. Slover Asset Optimizer builds and checks each bundle before it replaces the original files, so a failed build leaves the site exactly as it was.
What it does
Fail safe CSS bundling
The bundle is built and verified before anything is swapped.
Automatic critical CSS
Chosen from the theme sections each page uses.
Script delay
Tag managers and trackers wait for the first tap, scroll or key.
Long cache headers
One year immutable caching for bundled files.
Priority hints
fetchpriority tuning for the images and files that matter first.
Cache preloading
Warms every sitemap URL nightly or on demand, and flags broken links.

Questions
Will it break my site?
It is built not to. Each CSS bundle is verified before it replaces the original files, and a failed build leaves the site unchanged.
Does it delay Google Tag Manager?
Yes. Scripts like Google Tag Manager can wait until the visitor's first interaction.
Does it preload the cache?
Yes, from the sitemap, nightly or with a button, purging and warming each URL.
