 **Problem**: The `wp_add_inline_style()` function in `wp-
 includes/functions.wp-styles.php` lacks validation for the `$data`
 parameter, expected to be a non-empty string containing CSS. Invalid input
 (e.g., `null`, array, or empty string) could cause PHP notices or
 unexpected behavior in `WP_Styles::add_inline_style()`.

 **Proposed Fix**: Add a type and emptiness check with `_doing_it_wrong()`
 notice and return `false` on failure.

 **Reasoning**:
 - Prevents errors from invalid input.
 - Aligns with WordPress API validation practices.
 - Backward-compatible, only affects invalid calls.
