   There is deliberately NO global reset: the system never rewrites the host
   page's box model. Components are border-box instead, scoped to the `ip-`
   namespace so nothing outside it is touched. Without this, `width: 100%` plus
   a component's own padding spills past its container — it made `.ip-modal` run
   34px past a 375px viewport and `.ip-input` 6–8px past its field.
