   Trigger button (shared)

   Minimal native-button reset only. Decorative styling (color,
   background, padding, border-radius, shadow, sizing, typography)
   is intentionally left to the host theme so the trigger can adapt
   to wherever the shortcode is placed (menu, sidebar, body, etc.).
   The plugin only contributes:
     - a clean reset so it doesn't render as a default native button
     - inheritance of the surrounding text styles
     - transitions and animation effects (lift / scale)
     - an accessible default focus ring (themable via currentColor)
