   These links are deliberately quiet: the page pushes the $10 trial and the call
   is a conditional escape hatch. Quiet is a visual decision, not a reason to ship
   a 15px tap target on a page that is ~94% mobile. Padding expands the hit area to
   44px and the negative margin cancels the layout shift, so nothing moves. */
