/**
 * TC Searchbar — frontend styles.
 *
 * Themable via CSS custom properties (override them on .tc-searchbar or
 * any ancestor). Layout follows the design direction: a large rounded
 * white pill with a query field, a vertical divider, a taxonomy select
 * and a green pill-shaped submit button.
 *
 * Sizing strategy (Automatic.css friendly):
 *  - Font sizes and spacing prefer ACSS variables (--text-*, --space-*)
 *    and fall back to em values on sites without ACSS.
 *  - No raw rem values: themes that rescale the root font size (e.g.
 *    ACSS sites where 1rem ≈ 10px) would shrink the component. The em
 *    fallbacks track the component font size instead.
 *  - No max-width: the bar fills its container — wrap the shortcode in
 *    your own wrapper/section to constrain it.

 * panel loses `position: absolute` it drops into normal flow: the section
 * stretches to fit it and its z-index is ignored (z-index only applies to
 * positioned boxes), so it ends up overlapped by the section below — no
 * matter how high the value is raised.
 *
 * Pin the panel as an overlay with selectors specific enough to win that
 * cascade. These only restate the layout already declared above; they add
 * no new behaviour. The form is kept as the panel's positioning context so
 * the overlay always anchors to the bar. */
