 * Consume a simple block, CSS Syntax Level 3 [§5.4.9](https://drafts.csswg.org/css-syntax/#consume-simple-block) — the next token must be `(`, `[`, or `{` (asserted); consumes component values via `consumeAComponentValue` until the mirror closing token (`)`, `]`, `}`) or EOF, returning the partial block on EOF (parse error).
