How does !important affect the order of origins?

!important moves a rule to the very top of the cascade within its origin, meaning it forces the browser to apply that property over regular rules, even if they have higher specificity.

Simplified order (from weakest to strongest):

1. Regular browser styles
2. Regular user styles
3. Regular author styles
4. Author styles with !important
5. User styles with !important
6. Browser (user agent) styles with !important (almost never seen)

So !important effectively creates a separate "layer" on top of the regular rules, but within that layer, specificity and declaration order still apply.

Summary: !important sharply boosts a rule's place in the cascade chain, but it does not cancel out specificity among other !important rules.
