assertStyles

Prefer assert.ok() over assert() for explicit intent and better readability.

✅ This rule is included in the node stylistic and stylisticStrict presets.

Using assert.ok() aligns with other assert methods, ensuring consistency and making code easier to maintain and understand. The explicit method call clarifies the assertion’s purpose, making it immediately clear that a boolean check is being performed.
