Floating continue

Sticky-bottom call-to-action — a pill button wrapped in a frosted-glass container. Drop it at the viewport bottom so the primary next step is always one tap away.

Preview
Mock page content with the block anchored at the bottom of the preview area.
Back + Continue
Two actions in the same floating shell. On mobile the back label collapses to just the arrow to save space.
Back + Clear + Continue
Three-action variant. The middle Clear button is hidden on mobile to keep the shell compact.
Variants
Short label, no icon, and in-flow rendering.
