• 7b0d12b: feat(divider): the v1 Divider — no variant, one alignSelf for both axes

  The thirteenth entry of the core. One node and no slots: a rule is a filled box one point thick, and there is nothing inside it. A divider with a word across it is a Row holding two of these and a Typography — the composition the library already has. A Divider.Label would put a layout inside a line.

  No variant, and this is the only component in the core without one. A variant is the design system's vocabulary (§1 bis) — a name that means the same thing everywhere it appears — and on a rule there is nothing for such a name to describe: no fill against a foreground, no border against a surface, no intent to report. It briefly had three, naming the three separator tokens, which is a shade of grey wearing a word. size says how heavy the rule is and color says what colour it is, in React Native's own values; between them there is nothing a third name would add. The theme still sets the default — the rule paints separator.

  alignSelf: 'stretch' serves both orientations, and that one line is the whole mechanism: in a Column the cross axis is horizontal so a stretched child is full width, in a Row it is vertical so the same word makes a vertical rule full height, and on the axis the thickness fixes it is ignored. So there is no width or height to keep in sync, and a horizontal divider written inside a Row collapses on purpose rather than guessing.

  That is also why the recipe has no size × orientation compounds: the size axis writes both keys blind and the orientation axis, declared second, releases the wrong one. Four lines and two, instead of eight.

  asChild is there as R12 requires, and it earns its place on this component: an Animated.View that collapses a section takes the thickness and the ink from the recipe and the height from a shared value.

  size is the thickness — xs is the reference implementation's thin, one device pixel, and lg is their thick, six points. It defaults to xs, the one place in the library that does not default to md: a rule you notice is a rule that is too thick.
