/* The shell canvas keeps a final `min-height: 100vh` (see shell.css) — that is
   the large viewport, so on iOS Safari / Chrome Android in browser mode the
   bottom `100vh - 100svh` of the scroller sits under the browser toolbar and
   cannot be reached (html/body never scroll). The onboarding inline dock is the
   last flow element, so on long steps its CTA stays locked in that strip.
   Reserve exactly that hidden tail as scroll padding — the CTA can then be
   scrolled up into view. Scoped to onboarding on purpose: this only lengthens
   one scroller and touches no box geometry, so the shared bottom dock and every
   other screen stay untouched. Collapses to 0 where vh == svh (PWA, desktop). */
