/**
 * NAM-1450: accessibility props for the paywall image element (WCAG 1.1.1).
 *
 * A non-blank `alt` on the template's image component opts the image into screen
 * reader exposure: accessible element, image role, label = alt (raw — no smart-text,
 * matching the Web SDK's `<img alt>` handling). Anything else keeps RN's default
 * `accessible={false}`, i.e. the image stays decorative.
 *
 * RN-free module so the jest node environment can unit-test it (see
 * tests/components/elements/textInputStyle.test.ts for the pattern).
