Generate a quick visual mockup of an app screen for: $ARGUMENTS
- Read
DESIGN.mdfirst — use its tokens, components, and patterns exactly (colors, spacing, buttons, cards, empty states, page header/shell). Never invent new colors or fall back to generic Tailwind defaults. - Render the mockup as a single self-contained HTML file (inline CSS using the
victory-*hex values fromDESIGN.md) and publish it with the Artifact tool so it's viewable in the browser. - It's a static visual mockup, not a working page — no real data fetching or routing. Use realistic placeholder content instead of lorem ipsum.
- Match the mobile-first frame:
max-width: 32remcentered, darkvictory-bgbackground, bottom nav bar if the screen is a primary tab (Home/Train/Feed/Profile/etc).
Output: one Artifact link. Don't dump the markup in chat.
