   FormRenderer — public-facing dynamic form styles
   Used by src/components/ui/FormRenderer.tsx and any DOM that
   uses the .form-renderer__* classnames.

   Every visual property below resolves through the
   `--site-control-*` token contract (see
   src/lib/themeContract.ts § Form controls). Editing one of the
   tokens via the design panel retints every form-renderer input
   on every site. Element-local overrides may still chain through
   `--el-form-control-*` per element instance.
