Bottom Sheet
A panel that rises from the bottom of the screen: share, filter, pick a variant — thumb-reachable, swipe down to dismiss.
Every building block has a standard name, a pattern it belongs to, and a prompt you can hand to your AI. Pick a pattern on the left to filter.
One piece of content per card: media on top, title and summary below, one or two actions.
The primary navigation bar fixed at the bottom of a mobile app: 3–5 destinations, icon over label, thumb-first.
