/*
 * ART Banner — responsive hero banner.
 * Design: normal document flow (flex/grid), not absolutely-positioned layers, so content can
 * never overlap or get clipped at any screen size or orientation — the bug this replaces.
 *
 * Colors/radius consume the shared rcrr design-token layer (astra-child :root) via var(..,fallback),
 * so this plugin matches the site automatically when those tokens exist, and still looks right
 * (using its own sensible defaults) on any other site where they don't.

   (0,1,1) that the banner would otherwise inherit when placed inside post content. A portable
   component must own its own type scale regardless of the host theme, not rely on the theme
