   Chabela Cakes — base + shared primitives (owned by the design-system piece)
   1. Reset & element defaults   2. Typography helpers   3. Utilities
   4. Primitives (all prefixed .ds- so they never collide with component CSS):
      .ds-btn  .ds-chip  .ds-badge  .ds-field/.ds-input  .ds-stepper  .ds-segmented
      Choice controls (option chips, segmented) are <label>s wrapping a real
      <input type="radio">: arrow keys, one tab stop and form semantics come for free.
