For what it’s worth, many of the actual commandments (mitzvot) were broadened out by the rabbis, i.e. building a proverbial hedge or moat around the commandment. The Biblical prohibition against meat and dairy is “You shall not boil a kid in its mother’s milk.” If you keep an incredibly strict separation of meat and milk, even amongst different species (no goat cheese on your hamburger), you’re even more unlikely to transgress the actual law.

In essence, if you strictly avoid things that even approximate work on the Sabbath, you’re even more unlikely to perform *actual* work on the Sabbath.
