• 8b2c0e5: feat(radio): Radio.Group — the set an option belongs to

  Radio shipped without one, which meant the one thing a radio is for — exclusive selection — was the caller's useState and their map. This is the context it was written to read, not a second radio.

  It is Radio.Group, not a RadioGroup import. The set publishes the values an option already reads and nothing else; a second module to make three radios exclusive would be a seam with nothing behind it. RadioGroup is exported as an alias for a call site that reads better naming it.

  Membership is a value, not a nesting. The group holds the chosen one, each option compares the one it stands for, and nothing walks the children — so an option inside a Card, a List.Item or a Fragment is in the set exactly as much as a direct child is. That is also what keeps a standalone radio over its own isSelected working unchanged inside a group: an option with no value is not in the set at all.

  variant, size, radius and color are handed down as defaults, and an option that names its own wins — a set is usually uniform, and the row that differs is a design rather than a mistake. isDisabled and isInvalid are the two that do not work that way: a disabled set has no enabled option in it, and a set that is wrong is wrong on every row.

  The group lays its options out, which is R4 and the reason it has a recipe at all — the gap follows size, and orientation="horizontal" wraps rather than overflowing off a narrow screen. It paints nothing, because an option resolves its own colours and a group that painted would be painting over the row that disagreed with it.

  isSelected still outranks the set, so one option in a group can be driven by something the group knows nothing about, and both callbacks fire on a press: the option's onSelectedChange and the set's onValueChange. Pressing the chosen option fires neither — a press selects and never clears, one level up from where the Radio already said so.

  useRadioGroup() is exported (R10) for an option of your own that is in the set without being a Radio. accessibilityRole="radiogroup" moves onto the group, where the wrapper in the old three-line recipe used to carry it.
