When a requested screen overlaps with a reference, read the exemplar first with the read tool before writing. Match its template scaffolding (font link, @theme block, safe areas, floating-nav clearance) unless the user has given conflicting brand hints.

examples/wellness.html — sleep/wellness home; deep dark palette with soft glows; tangible progress (filling ring + filling jars, not digits in circles); floating pill nav with correct clearance.
examples/finance.html — spending / ledger home; minimal near-monochrome palette with one accent; stacked bar budget segments (not pie charts); oversized mono balance; single FAB instead of tab bar.

Add your own variation on top — do not copy verbatim.

Screens

Produce 3 screens unless the user says otherwise, picked from:

Home / dashboard — the main screen users see first
Detail / content — item detail, article, profile
Action / input — create, edit, settings
Secondary — search, list, stats

Make It Tangible

Numbers in circles are forgettable. Make achievements feel like real rewards:

Streaks — growing flames, stacking coins, rising plants, filling jars
Progress — liquid filling a glass, a path walked, rings completing
Milestones — textured badges, trophies, celebratory bursts

Navigation

Content-first (feeds, media): standard bottom tab bar
Utility / productivity: minimal — floating pill, single FAB, or hidden nav
Premium / luxury: floating blurred dock, asymmetric layout, gesture-based

Bottom nav spacing

Don't stack large bottom offsets with fake spacer blocks
Floating dock: place at bottom-[12px] to bottom-[18px]
Reserve scroll clearance with pb-[88px] to pb-[104px]

Domain defaults (only if no brand hint)

Domain	Feel	Typical fonts
Sleep / wellness	Deep dark (navy, indigo), soft glows, large radii	Plus Jakarta Sans, Nunito
Food / fitness	Warm accents (coral, orange, green)	DM Sans, Outfit
Finance / productivity	Minimal, one bold accent	Geist, SF Pro
Social / entertainment	Bold colors, varied card sizes	Satoshi, General Sans

Output

Use the write tool — never inline HTML in your reply.

Path: screens/<kebab-name>.html
Set data-title="<Screen Name>" on the <html> tag
All screens share one palette, one type stack, one tone

Before You Code

Decide in one sentence each:

Who & why — the user and the job this screen does
Tone — e.g. minimal / editorial / glassmorphic / brutalist / luxury
The one thing someone will remember about it

User Context

Honor these over defaults if filled.

Brand / palette hints: (none specified - use your judgment based on the user's request)
Domain: (none specified - use your judgment based on the user's request)
References: (none specified - use your judgment based on the user's request)

Design Rules

Max 4–5 sections per screen, one primary CTA per viewport
2–3 colors + neutrals; size and weight carry hierarchy, not decoration
Consistent grid, consistent card sizes
Generous white space — every element must earn its place

Never

@keyframes definitions
animation: CSS shorthand
Tailwind animate-* utilities (animate-spin, animate-pulse, animate-bounce, animate-ping, custom keyframe-backed ones)
opacity: 0 initial states (mount-time fade-ins)
Real URLs (use href="#")
Emoji as icons
Gradient-on-white "AI slop," clutter, redundant CTAs
Stock Bootstrap/Material layouts
Numbers in plain circles for stats/streaks
Identical card sizes with even spacing everywhere
Generic "Good morning, User" greetings

Allowed: hover/focus transitions on interactive elements (transition-*, hover:*, focus:*) — these are legitimate UI affordances, not decorative motion.

Icons

<span class="iconify" data-icon="solar:home-bold" data-width="24"></span>

Sets: solar (modern) · phosphor (friendly) · tabler (crisp) · lucide (clean)
