================ ONE-SHOT BUILD CONTRACT (read first) ================
Build this in Google AI Studio "Build" in ONE shot — a complete, working app,
no follow-up turns. These are hard rules, not suggestions:
1. TARGET = Full-Stack Web (Node server runtime, secrets, Firebase allowed).
If you target Native Android instead, you MUST drop all server/DB/Workspace/
secrets and persist locally (Room / SharedPreferences) only.
2. PIN EVERY MODEL CALL — never let the agent auto-select (it downgrades on quota):
- Reasoning / text -> gemini-3.5-flash (thinkingLevel: minimal|low|medium|high)
- 4K image + legible text -> gemini-3-pro-image (image_size "4K", up to 14 refs)
- High-volume image -> gemini-3.1-flash-image
- Expressive TTS -> gemini-3.1-flash-tts-preview (inline tags e.g. [whispers])
- Realtime audio/video (WebSocket) -> gemini-3.1-flash-live-preview
- Sandboxed agent -> antigravity-preview-05-2026
3. DIVISION OF LABOR — the model ONLY parses/extracts to a strict responseSchema.
ALL math, money (store currency as integer minor units / cents), sorting,
balancing and graph logic run in deterministic TypeScript/Python. The model
must never compute totals, splits or balances itself.
4. responseSchema sanitation — no regex patterns, no fixed-length tuples, no
format validators in the schema (they crash the OpenAPI engine). Enforce those
in server-side code AFTER parsing the JSON.
5. responseSchema and google_search grounding are MUTUALLY EXCLUSIVE in one call.
6. CODEGEN — split large output into modular, single-responsibility files so no
file is truncated by the output-token cap.
7. Every external call gets a graceful fallback (e.g. manual paste if a Workspace
read fails). Never a silent dead end.
8. ROBUST STORAGE & CANVAS — Wrap all `localStorage`/`sessionStorage` operations (especially JSON parsing and writes) in `try-catch` blocks to prevent crashes in private windows or quota overflows. Canvas drawing elements must dynamically handle window resize and scale pixel density (`window.devicePixelRatio`) to avoid blurry graphics on retina displays.
=====================================================================
# MUST OBEY — Mobile-first build requirements
This app's PRIMARY surface is a mobile phone. Build it impeccably on mobile FIRST, then verify on tablet and desktop. Treat the rules below as non-negotiable hard constraints, not suggestions.
## Viewports to verify (every screen, every state)
- 320 px, 360 px, 375 px, 390 px, 414 px, 480 px
- 768 px, 834 px (iPad portrait / Pro 11)
- 1024 px, 1280 px, 1440 px, 1920 px, 2560 px
- Plus: 200% browser zoom, landscape orientation on every mobile width, iPhone with safe-area insets visible
## Hard layout rules
- Mobile-first CSS. Default styles target mobile; `@media (min-width: ...)` for larger viewports.
- Use `dvh` and `svh` instead of `vh` for full-height surfaces (iOS Safari URL-bar bug).
- Use `clamp()` for fluid typography across all viewports.
- Prefer container queries (`@container`) over media queries for component-level responsiveness.
- Use `min(100%, ...)` widths so content never overflows. Zero horizontal overflow at any viewport.
- Add `` to every page.
- Apply `padding: max(safe-area-inset-X, fallback)` on every edge-bleeding container so notched iPhones in landscape never clip content.
- Wide tables and code blocks scroll INSIDE their container (`overflow-x: auto`), never push the body.
- Use `background-attachment: scroll` on mobile, not `fixed` (iOS Safari repaint bug).
- Avoid `backdrop-filter` on animated elements. Use it sparingly on static surfaces only.
- **Canvas Scaling**: Canvases must dynamically scale with window resize events and properly handle high-DPI screens (`window.devicePixelRatio`). Set physical dimensions (`canvas.width`/`canvas.height`) using pixel ratio and render relative to this grid, using CSS to control responsive viewport scaling.
- **Robust Storage**: Every access to `localStorage`/`sessionStorage` (especially `JSON.parse` of loaded state or writes) MUST be wrapped in a `try-catch` block to handle disabled storage, private browsing mode, quota limits, or corrupted JSON gracefully. Fall back to a robust in-memory object store.
## Touch & accessibility
- Tap targets ≥ 44 × 44 px on touch (Apple HIG). Increase to 48 px under `@media (hover: none) and (pointer: coarse)`.
- All interactive controls reachable by keyboard with a visible focus ring; respect `:focus-visible`.
- Color contrast ≥ 4.5:1 for body text, 3:1 for UI components.
- All images have meaningful `alt`. Decorative images use `alt=""`.
- Respect `prefers-reduced-motion: reduce` — zero animation durations under that query.
- Forms validate inline; error messages are specific, not "Invalid input".
- Modals: focus trap, `Esc` closes, `role="dialog"`, `aria-modal="true"`, focus restored on close.
## Performance bar (Lighthouse mobile, throttled 3G/4G)
- LCP < 2.5 s · INP < 200 ms · CLS < 0.1
- JS bundle gzip < 200 KB mobile-first; lazy-load non-critical screens via `React.lazy` / dynamic imports.
- No render-blocking resources above the fold.
- Images: WebP/AVIF preferred, `loading="lazy"`, explicit `width`/`height` attributes (zero CLS), `srcset` for retina.
- Videos: `preload="metadata"`, low-resolution poster, max 720p mobile fallback. Never autoplay with audio.
- Fonts: `font-display: swap`; preload only the one used above the fold.
- Smooth scroll honoured via CSS `scroll-behavior: smooth` with reduced-motion fallback.
## Pre-ship mobile checklist (the deployer MUST verify before declaring done)
1. Open at 375 px in DevTools — every screen scrolls vertically only; zero horizontal scroll.
2. Browser zoom 200% — layout reflows without overlap.
3. iPhone Safari with the URL bar visible AND landscape — no content under the home indicator; no notch clipping.
4. iPad portrait (768 px) and landscape (1024 px) — no awkward gaps; tablet-specific breakpoints land cleanly.
5. Tap every interactive element with a thumb at real-device size — every target is easy to hit.
6. `prefers-reduced-motion: reduce` — every transition / animation skips cleanly, scroll-behavior becomes instant.
7. Lighthouse mobile score ≥ 90 across all 4 categories.
8. Zero `console.error` and zero CLS shift in real-device testing on a mid-tier Android (e.g. Pixel 6a) and an iPhone SE.

# Build Prompt — Artist Gallery Portfolio
Paste this into Google AI Studio's **Build** function. It is self-contained — every section below is part of the instructions.
_Source reference: https://lovable.dev/templates/websites/portfolio/portfolio-template-2_
---
## 1. Project
Build a **Portfolio** named **Artist Gallery Portfolio**.
One-line description: _Launch a gallery-style portfolio that matches your work quality—live in hours, not weeks. Showcase projects with smooth animations and professional design that justifies premium pricing._
**What it is:**
This template gives you a gallery-style portfolio with warm beige aesthetics and smooth animations, and you don't need design skills or coding knowledge to make it work.
The technical parts are already handled. Your portfolio works beautifully on any device, loads quickly even with large image files, and gets found by clients searching for your services—all done. You can focus on showcasing your best work and telling your story instead of wrestling with code.
Images gradually come into focus and elements respond smoothly as visitors browse. These details create the professional experience that makes clients take your work seriously and helps justify the rates you deserve.
## 2. Target audience
- Freelance photographers and visual artists building their professional presence to compete for premium client projects
- Creative consultants and service professionals who need their portfolio to justify premium pricing and demonstrate attention to detail
- Design agencies showcasing client work and case studies to win competitive pitches
- Small creative studios presenting projects with the same polish they bring to client deliverables
- Established creatives upgrading from generic website builders that make them look like everyone else
- Independent artists building their first professional online presence with gallery-quality presentation
## 3. Core value propositions
Surface these clearly through copy, visual emphasis, and section ordering — they are the reasons users pick this product.
- **Gallery-Quality Visual Experience** — Physics-based interactions and progressive image loading create premium portfolio feel
- **Professional Artist Presentation** — Editorial typography and warm palette designed specifically for creative portfolios
- **Mobile-First Responsive Design** — Seamless experience from desktop sidebar to mobile overlay across all devices
- **Lightning-Fast Performance** — Optimized animations and lazy loading deliver sub-2s page loads consistently
- **SEO & Discovery Ready** — Built-in meta tags and Open Graph integration help collectors find work
- **Fully Customizable Foundation** — TypeScript codebase with sixty-plus components enables unlimited creative extension possibilities
## 4. Features to build
**Product features:**
Production-ready features built with modern tech stack for exceptional performance and user experience
- Custom Physics Cursor
- Progressive Image Loading
- Staggered Entrance Animations
- Responsive Sidebar Navigation
- Premium Typography System
- Warm Gallery Palette
- SEO-Optimized Architecture
- Artwork Detail System
- Performance Optimized Build
- TypeScript Foundation
- GitHub-Ready Export
## 4b. Required services & integrations
List the back-end services this template needs to function. If a service is not needed, say so explicitly — silence is ambiguous.
- **Auth — Not needed.** Portfolio sites are public.
- **CMS — Light.** Optional headless CMS for case studies; static MDX-in-repo also fine.
- **Image CDN — Required.** Hi-res photography served via Cloudinary/Imgix with srcset + AVIF/WebP.
- **Payments — Not needed.**
- **Transactional email — Required.** Inquiry form → routed to inbox + auto-acknowledge reply.
- **External APIs — None required.**
**Environment variables to expose in the build:** mark every secret (API key, DB URL, JWT secret, Stripe key, S3 credential) as a clearly named `.env` variable — never hard-code. Include a `.env.example` with the full list.
**Auth + data privacy reminders:** never log secrets · never store passwords in plain text · use HTTPS everywhere · hash + salt with bcrypt or argon2 · refresh tokens with rotation · honor a 'delete my account' request inside the UI.
## 5. Use cases & content to include
Build dedicated UI sections or pages for each of these — they tell you what content the page must support.
- **Professional Portfolio Site** — Present your work with gallery-style layouts and smooth animations. Showcase your projects clearly with progressive image loading and responsive grids. Clients who are comparing you to competitors will notice the difference between a professional portfolio and a basic template site.
- **Visual Artist Portfolio Showcase** — Display artwork with detailed project pages that tell the complete creative story. The responsive grid layouts work well for gallery presentations, complete project documentation with process work, and exhibition highlights. When you're building your artistic reputation, showing the full context and story behind each piece demonstrates capability better than static presentations.
- **Freelance Services Portfolio** — Attract better clients by presenting your work professionally. The clean layouts and professional design support your premium positioning because your portfolio demonstrates the same attention to detail you bring to client projects. The dark mode support means your work looks great regardless of how prospects browse.
- **Artist Portfolio with Custom Business Presence** — Build a professional portfolio platform with integrated business functionality. This template features responsive navigation that works on desktop and mobile, with layouts that present your work clearly. The warm beige gallery aesthetic showcases your work beautifully while providing prospects with service information and direct contact access.
## 6. Recommended page structure
Generate the following sections in this order. Adjust labels to fit the brand voice, but keep the structural intent.
1. Hero — name, role, one-line positioning, optional portrait.
2. Selected work grid — 4–8 case studies with thumbnail + title + tags.
3. Case study detail layout — challenge, approach, outcome, large imagery.
4. About — bio, services / skills, clients list.
5. Contact — email + form, social links.
6. Footer.
## 6b. First-visit onboarding
Show a **first-visit onboarding** the first time a visitor lands on the site
(detect via `localStorage` flag; do not show on return visits). Keep it
short — three steps maximum — and respectful: visitors can dismiss at any
time and revisit later from a `?` icon in the header.
**Format:** a polished modal *or* a 3-step inline tour, designed to match the
overall visual style of the template (don't bolt on a generic stepper UI).
On mobile, full-screen sheet that slides up.
**Required content — three slides:**
1. **What this is.**
- One-line headline: "Welcome to *Artist Gallery Portfolio* — a template for Launch a gallery-style portfolio that matches your work quality—live in hours, not weeks. Showcase projects with smooth animations and professional design that justifies premium pricing."
- One paragraph (max 60 words) explaining what the template demonstrates,
who it's for, and what you'd typically use it for.
- Visual: a small annotated screenshot of the page they're about to see,
OR a 4-frame storyboard of key sections.
2. **What to try.**
- 2–3 specific things the visitor should look at to understand the design
(e.g. "Open a section to see the booking flow", "Hover the gallery for
captions", "Resize the window — every layout is fluid").
- Reference real elements on the actual page so the visitor learns by doing,
not by reading.
3. **How to remix this.**
- A direct CTA: "Use this template" → links to Lovable / AI Studio Build
remix entry point.
- Below: 3 short bullets on how to make it yours — e.g.
• "Swap the copy in `data/content.{ts,json}` for your own."
• "Replace the imagery in `/public/images/` (we use AVIF + WebP)."
• "Connect your services using the env-var list in section 4b above."
- Plus a quieter secondary action: "Just looking — close" (closes modal,
remembers preference in localStorage, never auto-shows again).
**Persistent re-entry point:**
A small "?" icon in the top-right header next to the primary nav. Click → reopens the onboarding from slide 1. Tooltip: "How this template works".
**Accessibility:**
- Trap focus inside the modal while open
- `Esc` closes
- All controls reachable by keyboard, visible focus ring
- Heading hierarchy: modal title is `h1` inside the dialog
- `role="dialog"` + `aria-modal="true"` + `aria-labelledby`
- Restore focus to the trigger (or to ``) on close
- Respect `prefers-reduced-motion` — fade in/out only, no large transforms
**Copy tone:**
Warm and direct, not corporate. Avoid "Welcome to your dashboard" language.
Avoid all caps. Use the same voice as the rest of the template's copy.
**Don't:**
- Don't gate content behind the modal. The page below must be fully scrollable.
- Don't show the modal again on return visits. Use `localStorage['onboarding-seen']`.
- Don't include marketing CTAs unrelated to remixing (no newsletter signup, no
"follow us on X" — those live elsewhere).
## 7. Design language
- **Mood:** Editorial, image-led, confident. The work is the hero — UI recedes.
- **Typography:** A display serif (Fraunces, Tiempos, GT Sectra) + clean grotesque body. Use a clear modular scale (e.g. 12 / 14 / 16 / 20 / 24 / 32 / 48 / 64 px) and tight tracking on display sizes.
- **Palette:** Off-white or paper backgrounds; one strong neutral; restrained accents.
- **Spacing:** consistent 4-px base. Generous whitespace — let the content breathe.
- **Radius:** consistent token set (e.g. 6 / 12 / 20 px). Don't mix arbitrary values.
- **Shadows:** subtle, layered. Avoid heavy drop-shadows.
- **Imagery:** Hero project image must look real and high-end. Use curated stock (Unsplash editorial) or describe a generation prompt that matches the genre.
- **Motion:** purposeful — entrance fades, hover lifts, page transitions. Respect `prefers-reduced-motion`. No bouncing splash animations.
## 8. Content generation rules
- Write **realistic, specific copy**. NO Lorem Ipsum. NO generic placeholders like 'Your tagline here'.
- Invent plausible names, dates, locations, prices, quotes, testimonials and product details that fit the domain.
- Tone should match the audience above — confident, specific, free of buzzwords.
- Headlines: punchy and concrete. No 'Empower your business' filler.
- Body copy: short paragraphs (2–4 sentences). Use lists where appropriate.
- All numbers, stats, and metrics must look plausible for the domain.
## 8a. Seed content (use these specific examples)
Anchor the generated copy in the concrete data below. Use these names, numbers, dates, and snippets verbatim where helpful, or generate close variants that sit in the same world.
**Artist identity:** Gallery — Iris Pomar — visual artist (oil + mixed media) · Berlin · 12 years · represented by Sprüth Magers (Berlin/LA)
**Hero image:** "Untitled (Cathedral), 2026, oil on linen, 220 × 180 cm"
**Featured galleries (8 sections):**
1. **2026 work — current** — 12 pieces — oil on linen — themes of architecture + interiority
2. **2025 — Cathedrals** — solo show at Sprüth Magers Berlin — 18 pieces
3. **2024 — Slow Light** — solo show at Tanya Bonakdar NYC — 14 pieces
4. **2023 — Architecture of the Hospital** — Whitney Biennial — 9 pieces
5. **Drawings 2021-2026** — 88 works on paper
6. **Sculpture (2022-now)** — 14 small bronzes + 3 large outdoor commissions
7. **Public commissions** — 4 site-specific works (Hong Kong, Berlin, Mexico City, NYC)
8. **Archive 2014-2020**
**Gallery representation:** Sprüth Magers (primary) · Tanya Bonakdar NYC · kurimanzutto Mexico City
**Recent acquisitions:** MoMA New York · Tate Modern · Centre Pompidou Paris · Kunstsammlung NRW Düsseldorf · Hammer Museum LA
**Press strip:** "Featured in *Artforum*, *Frieze*, *Mousse*, *Texte zur Kunst* · *NYT* profile 2024"
**Upcoming:** "Solo show — Pirelli HangarBicocca Milan — September 2026 · 'Slow Architecture' — 24 new works"
**CV PDF download:** "Full CV — exhibitions, residencies, prizes, education, public collections"
## 9. Media & assets
Every ``, `background-image`, gallery tile, thumbnail, and decorative figure on the page must come from ONE of the three buckets below. Do NOT reference any image path that is not specified here. Do NOT ship stock-photo placeholders.
### Bucket 1 — Runtime-generated via Nano Banana Pro (`gemini-3-pro-image`)
Generate at build time, cache to Firebase Storage at the path listed, serve via signed URL. Each call uses model `gemini-3-pro-image`, output format `image/webp`, dimensions as listed. The visual register matches section 7 (Design language) and the specific seed content in section 8a.
- **Hero image** → `/public/generated/hero.webp` · 2400×1500 · prompt: "Editorial hero portrait or signature-project shot of the creator named in section 8a. Visual register of section 7 — typically minimal, image-led, soft natural light. If a portrait, neutral background; if a project shot, framed to feel inhabitable rather than rendered. No on-image text, no logos."
- **Project thumbnails (one per case study in section 8a, typically 6-8)** → `/public/generated/projects/{project-slug}/thumb.webp` · 1600×1200 · prompt: "Per-project prompt built from the case-study title + location + year in section 8a, e.g. "Linden Hall, Cotswolds (UK) 2024, renovation + addition" → "editorial photograph of a Cotswolds country-house renovation, golden-hour exterior, stone facade with new glazed addition visible, 35mm look, no readable signage". One thumbnail per case study."
- **Project case-study detail images (4-6 per project)** → `/public/generated/projects/{project-slug}/detail-01.webp … detail-06.webp` · 2000×1333 · prompt: "Per-detail prompt expanding from the case-study facts in section 8a — exterior wide, interior wide, material close-up, plan/section sketch render, scale-with-figure. No on-image text."
- **About portrait** → `/public/generated/about-portrait.webp` · 1200×1500 · prompt: "Editorial portrait of the creator named in section 8a, natural light, neutral background, slight smile or neutral expression, no on-image text."
- **Studio / process photographs (4 tiles for the About / Process section)** → `/public/generated/studio/s-01.webp … s-04.webp` · 1600×1200 · prompt: "Documentary photographs of the studio space described in section 8a — drawing desk, model wall, materials shelf, team in conversation. No on-image text."
- **Wordmark / monogram** → `/public/generated/wordmark.svg` · prompt: "A simple personal wordmark for the creator named in section 8a, set in the display font of section 7, restrained and confident." Favicon export to `/public/generated/favicon-256.webp` (256×256).
### Bucket 2 — Seed assets shipped with the deliverable
Static files committed to `/public/samples/` as fallbacks when generation fails. Generated once via Nano Banana 2 (`gemini-3.1-flash-image`), 1024×1024 WebP unless noted.
- `/public/samples/empty-state-projects.webp` — 1024×1024 — prompt: "Minimal hand-drawn line illustration of an empty portfolio sleeve, single-stroke outline, no colour fill."
- `/public/samples/empty-state-contact.webp` — 1024×1024 — prompt: "Minimal hand-drawn line illustration of an empty envelope with one stamp corner, single-stroke outline, no colour fill."
- `/public/samples/hero-fallback.webp` — 1600×1000 — same prompt as the Bucket-1 hero, encoded once at build and committed so the page renders identically if Gemini quota is exhausted.
### Bucket 3 — User-supplied (when the template is remixed)
Onboarding modal surfaces a "Replace with your photos" hint. Uploads land via the file input → Firebase Storage path `portfolios/{creatorSlug}/projects/{projectSlug}/uploads/`. The build ships with Bucket-1 + Bucket-2 only; no user-supplied images at first paint.
### Hard rules
- Every `` tag MUST have a `src` that resolves to a path listed above. Any `` referencing a path not in this section is a build error.
- No bare `image.jpg` / `hero.jpg` / `placeholder.png` references anywhere in the code.
- Icons: `lucide-react` only; use sparingly and consistently — never decorative-only.
- Optimisation: WebP or AVIF, `loading="lazy"` on everything below the fold, explicit `width`/`height` to prevent layout shift.
## 10. Interactivity & states
- Every interactive element has a hover, focus, active, and disabled state.
- Forms validate inline and show specific error messages.
- Loading states (skeletons, not spinners where possible).
- Empty states with helpful next-action guidance.
- Smooth scroll for in-page anchors.
## 11. Tech & responsive requirements
- **File downloads on Safari / Firefox:** when offering local-disk save of any export (PDF, CSV, MP3, ZIP, JSON, image, `.ics` calendar invite), fall back to `` with a blob URL — the File System Access API (`showSaveFilePicker()`) is Chromium-only. Detect with `'showSaveFilePicker' in window`; otherwise use the anchor-download path.
- **Stack:** React + TypeScript + Tailwind CSS. Use functional components and hooks.
- **Mobile-first.** Verify layouts at 375 px (iPhone SE), 768 px (iPad), 1024 px, 1440 px+.
- Use `clamp()` for fluid typography where appropriate.
- Prefer container queries over media queries for component-level responsiveness.
- Use `dvh` / `svh` units instead of `vh` to handle mobile viewport chrome.
- Zero horizontal overflow at any width. Zero layout shift on load.
- Respect safe-area insets on iOS.
## 12. Accessibility (WCAG 2.2 AA)
- Semantic HTML — `header`, `nav`, `main`, `section`, `article`, `footer`.
- All interactive controls reachable by keyboard with a visible focus ring.
- Color contrast ≥ 4.5:1 for body, 3:1 for large text and UI components.
- All images have meaningful `alt` text. Decorative images use `alt=""`.
- Form fields have associated `
