 *
 * Layout strategy: the wrapper has a fixed visual height (46px) for border
 * + focus ring + theme resistance, BUT it uses flex centering so the iframe
 * is positioned by Clover's own auto-resize, not stretched to fill the wrapper.
 *
 * Clover's SDK does this internally (see sdk.js updateFrameStyles): the
 * iframe document measures its rendered content and posts {style, width,
 * height} back to the parent, which Clover then applies to the iframe element
 * inline. If we force height:100% with !important on the iframe, we override
 * Clover's measurement and force the viewport to 46px even when the iframe
 * document needs slightly more (e.g., sub-pixel rounding, focus ring inside
 * the iframe, masked-input wrappers Clover adds around the input element).
 * That is what produces the per-field scrollbars.
 *
 * Instead: let Clover size the iframe to its natural content height (the
 * input is height:46px via theme.ts), center it within our 46px wrapper
 * via flex, and clip any sub-pixel overshoot with overflow:hidden.
