Cascade layers
you put the vendor stylesheet in a lower layer and your one-class rule now beats its id selectors.
Named buckets declared with `@layer` that are compared before specificity, so an entire body of CSS can be placed above or below another regardless of how its selectors are written. It is the intended answer to the third-party override problem that `!important` used to be. The catch is that unlayered styles beat every layer, so partial adoption inverts the result you expected.

you could not work out why the rule was losing, so you added `!important` and moved on.
A flag that lifts a declaration into a higher cascade origin, above every normal declaration regardless of specificity. It works, which is the problem: the next person to hit the same wall has only one move left, and important declarations from user stylesheets and browser defaults follow their own reversed precedence. The one legitimate use is overriding styles from third-party code you cannot edit.
