RUM Data
- use that rum DATA to print suggestions on the admin page
-- for LCP maybe check attribution and closest ("[class]")
-- for img without dims just use the optimizer
- filtering on device and url level. Would cost a lot or resources though :-(

improve image conversion
- check for cwebp
- add option to rewrite html (CDN safe)
--- place img in picture tag or rewrite picture tags!
--- config button for picture tags
- test converter button

better default for script scheduler
- some scripts are never render critical (chat, like buttons etc etc)
