Roll dice using standard dice notation, returning the individual rolls and their total. Use for anything that genuinely benefits from a random outcome — decisions, games, random prompts, divination-as-play — not as a substitute for simply making up a number when one isn't needed. Accepts `NdS[+/-M]` where N is the number of dice, S is the number of sides, and M is an optional modifier. Examples: `2d6`, `1d20+5`, `4d6-1`, or `d8` for a single die.
