🛠️ Fix: Skip explicit undefined values in stringifyCSSProperties
This PR fixes #11 — handling cases where CSSProperties may contain value is explicitly set to
undefined.✅ Changes
Added a type guard to ensure only string or number values are processed.
Updated stringifyCSSProperties to skip properties with invalid values (undefined, null, objects, etc.).
Removed a test case that expected an error to be thrown for invalid input — since invalid values are now gracefully ignored.
Added new tests for undefined and null cases.
Added a publishing checklist doc (
docs/publishing.md) with manual publishing instructions.✅ Expected behavior
Previously, passing undefined values caused the lib to throw.
Now such values are silently skipped, ensuring safe and predictable behavior.
