/**
 * Converts a style object to a CSS style string.
 *
 * @deprecated Use `styleString` from `@humanspeak/svelte-motion` instead for reactive styles.
 * This function is non-reactive and will not update when values change.
 *
 * @param obj - Style object with camelCase keys and string/number values
 * @returns CSS style string with kebab-case properties and appropriate units
 * @example
 * ```ts
 * // Old (deprecated, non-reactive):
 * import { stringifyStyleObject } from '..'
 * const style = stringifyStyleObject({ rotate: 45, opacity: 0.5 })
 *
 * // New (reactive):
 * import { styleString } from '@humanspeak/svelte-motion'
 * const style = styleString(() => ({ rotate, opacity }))
 * ```
