theme-collision

A theme token whose name a built-in utility also uses.

• csszyx check reports it in its theme-collision pass.
• It is printed to the console. A production browser bundle leaves it out.

Message

A name in angle brackets is a value the message fills in.

classes

[csszyx] theme-collision: Theme token `<name>` also names `<classes>`, so Tailwind compiles both meanings into one rule, which sets the token's property and the built-in's.
  help: rename the token; while it shares a built-in name, no class order or `szcn` call can fix this.
  note: a later class that sets only one of them does not replace it in `szcn`, so both apply and stylesheet order decides which wins; `classify` reports the built-in meaning only.

utility-keyword

[csszyx] theme-collision: Theme token `<name>` shadows a built-in utility keyword, so Tailwind compiles both meanings into one class, which sets the token's property and the built-in's.

Level

Default: error under recommended, error under atomic. Set it in csszyx.config: rules: { 'theme-collision': 'warn' }.

The level sets how the build and csszyx check report it. It does not change a console line, and it does not stop a thrown error.
