 * + one-row form. The card IS the visual surface; root is transparent.
 *
 * Scope: all rules under #bw-subscribe-panel so nothing leaks.
 *
 * Palette tokens used (all real, defined by the customizer):
 *   --color-primary       brand colour (eyebrow, button, focus rings)
 *   --color-bg-soft       soft surface tint (card background)
 *   --color-bg            page bg (input bg, inverted card surface)
 *   --color-border        hairline divider
 *   --color-text-muted    muted body text
 *   --color-text-on-primary  button text colour
