Gamified App Skill

Produce a multi-screen mobile prototype on a single dark showcase page. Three phone frames side-by-side, each one its own moment in the journey.

Workflow

1. Read the active DESIGN.md (injected above). For gamified apps, lean on bold display type for headlines and a brighter, broader palette than most products — quests look like quests because the colors do.
2. Pick the brand + value prop from the brief. Generate real quest names (e.g. "Body — 20-min strength: pushups & planks", "Read — Four Thousand Weeks", "Listen — Huberman Lab · Sleep Architecture", "Nourish — Cook a high-protein lunch", "Mind — 10-min focus meditation", "Watch — The Bear · S3 E4").
3. Stage — full-bleed dark page (near-black #0e0d0c or DS dark token) with a soft top spotlight gradient. Above the phones, a small caption row: "HI-FI PROTOTYPE · IPHONE" left, brand wordmark right, both in mono.
4. Phones — three 360×780 phone frames in a horizontal row (wraps to stack on narrow viewports). Each phone:
   • 12px black bezel, 44px corner radius, dynamic-island notch.
   • Status bar (time / signal / battery).
   • Phone-specific content (below).
   • Bottom tab bar with 5 icons (Today, Library, Stats, ⊕ central CTA, Profile). Active tab in accent.
5. Phone 1 — cover poster (sales/value prop):
   • Status bar.
   • HI-FI PROTOTYPE · IPHONE eyebrow.
   • Big display headline ("Daily quests for becoming a better human."), accent on "becoming".
   • 1–2 sentence body in muted serif/sans.
   • Mono tip line ("Tap quests to open detail. Toggle [theme] in the toolbar to switch theme & layout.")
   • Subtle scrolling teaser of the next screen at the bottom edge.
6. Phone 2 — today's quests dashboard (the hero screen):
   • Greeting "Good morning, Sam" + small XP-bell ringing.
   • Level ribbon — "LV 14 · Level 14 · 1648 / 2480 XP" with a progress bar inside a glassmorphic ribbon.
   • Sub-line: "8 quests waiting · earn 430 XP today".
   • 3×2 grid of quest tiles. Each tile: rounded corner, pastel accent color, glyph chip in top-left, title, mini-meta line, "+NN XP" pill in bottom-right.
   • Bottom tab bar.
7. Phone 3 — quest detail:
   • Back arrow + screen title ("Quest").
   • Hero block with the quest's accent color, big serif quest title ("Body — strength"), short narrative body, "REWARD +90 XP" stamp.
   • Steps checklist (3–4 micro-tasks, one done, two pending).
   • Big primary CTA "Start quest" pill at the bottom in accent.
8. Write a single HTML document:
   • <!doctype html> through </html>, CSS inline.
   • All in CSS — no images. Use linear-gradient and inline SVG glyphs for tile chips and tab icons.
   • data-od-id on stage, each phone, each frame's regions.
9. Self-check:
   • Three frames, each with a distinct purpose. Not three copies of the same screen.
   • Tile colors don't overpower — each quest tile uses a different pastel against the same neutral surface.
   • Reads as gamified and adult — playful, not childish.

Output contract

Emit between <artifact> tags:

<artifact identifier="game-slug" type="text/html" title="Mobile — App Name">
<!doctype html>
<html>...</html>
</artifact>

One sentence before the artifact, nothing after.
