The "Gefällt es dir?" guest nudge was a free-floating fixed element at
bottom: 10rem, so it didn't follow the bottom-stack when the PillNav was
collapsed. Move it inside .bottom-stack as the first child so it shares
the stack's reflow.
NotificationBar now uses the elevation system (--color-surface-elevated,
--color-border-strong, --color-foreground) instead of hardcoded rgba so
it adapts to all themes. Bumped the CTA button (shadow + hover lift) and
container (stronger border, layered shadow) to be more visible.
