🟢check_feature_support(feature)

Can I use this feature, and from which browser version? Accepts a loose name (":has()", "container queries", "css-grid") and resolves it to a caniuse feature, then returns the earliest continuously-supported version per major browser, global usage percentage, and a conservative safe_to_use flag. Use this first; it answers the whole question in one call.
