================ 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. --- The original template starts below. All rules above apply on TOP of whatever this template specifies. --- # Build Prompt — Latin Urban Artist Site 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/music/fuego-latin-urban-artist-website-template_ --- ## 1. Project Build a **Music** named **Latin Urban Artist Site**. One-line description: _Bold modern artist website_ **What it is:** This template gives you an artist website that looks professional and you don't need design skills or technical knowledge to make it work. You get four main sections—music releases with streaming links, tour dates with ticket info, merchandise with pricing, and video galleries—all organized in clean layouts that work on any device. Your content stays front and center while the design handles the heavy lifting. The technical parts are already handled. Mobile responsiveness, smooth animations, streaming platform integration, ticket status tracking—all done. You can focus on uploading your content, connecting your links, and building your fanbase instead of wrestling with code. The dark aesthetic with bold red accents creates an urban edge that works for Latin artists, hip-hop performers, and genre-blending musicians who need something that stands out. Full-screen video hero, modern card designs, and professional typography give you a look that matches established artists without the custom development cost. ## 2. Target audience - Latin urban and reggaeton artists building their professional presence with a bold, modern design that captures their brand's energy - Independent musicians launching direct-to-fan platforms that showcase music, merchandise, and tour dates without intermediaries - Artists who need professional streaming presentation and booking agent credentials built into their core web presence - Touring musicians and bands promoting upcoming shows with integrated ticket sales and merchandise storefronts - Music managers handling multiple artist clients who need customizable, high-impact artist websites that stand out in a competitive landscape - Singer-songwriters combining music releases, visual content, and merchandise into a unified, professionally-designed platform ## 3. Core value propositions Surface these clearly through copy, visual emphasis, and section ordering — they are the reasons users pick this product. - **Professional artist presence** — Launch a polished music website in hours without design skills or technical knowledge. - **Complete music hub** — Showcase releases, tour dates, merchandise, and videos in one unified platform. - **Bold urban aesthetic** — Dark theme with vivid red accents creates standout visual identity for Latin artists. - **Mobile-ready galleries** — Three-column layouts collapse smoothly to mobile for perfect viewing on any device. - **Direct fan revenue** — Integrated merchandise displays and ticket links turn site visits into sales. ## 4. Features to build **Product features:** Production-ready features built with modern tech stack for exceptional performance and user experience - Full-screen video hero - Music release catalog - Tour date management - Merchandise storefront - Video portfolio gallery - Glass-morphism card design - Smooth page transitions - Related content discovery - Responsive grid layouts - Professional typography - Sticky navigation - Contact integration ready ## 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 — Optional.** Only for fan-club / paid-tier areas. - **Database — Light.** Tour dates, releases, video links, mailing-list subscribers. - **Image/video CDN — Required.** Album art, hero video, photo galleries. - **Payments — Optional (Required for merch).** Stripe checkout if merch shop included. - **Newsletter — Required.** Mailing list for tour pre-sales and release announcements. - **External APIs / third-party services:** - Spotify / Apple Music / Bandcamp / Tidal deep links - YouTube embeds for videos - Ticket vendor links (DICE, Eventbrite, Bandsintown, Songkick) **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. - **Music Release Hub** — Display your complete music catalog with album art and streaming links. The organized layouts help fans find and share your work, which drives streaming numbers up. Each release includes track listings and links to every major platform, making it easy for fans to listen wherever they prefer. Related releases at the bottom of each page keep fans exploring your discography longer. - **Tour Date Management** — Show upcoming shows with venue info, ticket prices, and clear sold-out or available badges. The presale, available, and sold-out indicators let fans know exactly what they can book. Venue details and direct ticket links turn your site into a conversion tool, not just an announcement board. You turn site visits into ticket sales by making the path from discovery to purchase frictionless. - **Merchandise Sales** — Sell vinyl, CDs, apparel, prints, and other physical products with category tags and pricing clearly displayed. Each item gets professional product photography treatment with detail pages that explain what fans are buying. Link directly to your payment processor so fans buy without friction, turning your site into a revenue stream that works while you focus on making music. - **Video Portfolio** — Feature music videos, live performances, and behind-the-scenes content with professional presentation that keeps fans engaged longer. Play buttons, video categories, and director credits give each piece proper context. The longer they stay on your site exploring videos, the more likely they follow you and share your content across their networks. ## 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 — full-bleed image / video, artist name, latest release CTA. 2. Latest release with cover art, tracklist, streaming links. 3. Discography grid. 4. Tour dates with venue + ticket link + status badges. 5. Video / media gallery. 6. Merch grid. 7. About / press kit. 8. Footer with socials and contact. ## 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 *Latin Urban Artist Site* — a template for Bold modern artist website." - 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:** Cinematic, atmospheric, photo-led. Heavy on imagery and motion. - **Typography:** Display serif or condensed sans for artist name; clean body sans. Use a clear modular scale (e.g. 12 / 14 / 16 / 20 / 24 / 32 / 48 / 64 px) and tight tracking on display sizes. - **Palette:** Often dark or duotone. Strong contrast between text and imagery. - **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:** Performance photography, album art, moody portraits. Vignette overlays allowed if requested. - **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:** Fuego · reggaeton + Latin hip-hop · San Juan, PR · 2 albums · 2.4M monthly listeners **Latest release:** "*Flicker*" — LP — April 12, 2026 · 14 tracks · 41 min **Lead single:** "*Vente Conmigo*" — #1 Latin Airplay (4 weeks), 88M Spotify streams in first 30 days **Discography:** - *Flicker* (2026) - *La Capital* (2023, certified 3× platinum Latin) - *Demos del Caserío* (mixtape, 2020) **Tour (arenas + festivals):** - Jul 14 — Coliseo de PR, San Juan — sold out (2 nights) - Jul 28 — United Center, Chicago — tickets · selling fast - Aug 02 — Kaseya Center, Miami — sold out - Aug 05 — Madison Square Garden, NYC — tickets - Aug 12 — KIA Forum, LA — tickets - Aug 22 — WiZink Center, Madrid — sold out - Aug 27 — Sant Jordi Club, Barcelona — sold out - Sep 04 — Lollapalooza Chicago — festival **Collaborations:** "Featured: Bad Bunny, Rauw Alejandro, Karol G, Tokischa, Tainy, Ozuna · Producers: Tainy, Bizarrap, Sky Rompiendo" **Press:** "★★★★ Rolling Stone · *Billboard* Cover (May 2026) · 2026 Latin Grammy: Best Urban Album (nominee)" **Merch:** "Tour windbreaker $98 · 'Flicker' chain $48 · Vinyl $42" ## 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: "Cinematic full-bleed photograph or live-performance still of the artist named in section 8a, in the visual register of section 7. Moody lighting, vignette acceptable. Real-photo aesthetic, 35mm or medium-format look. No on-image text, no logos, no readable festival signage. Composition leaves a clean lower-third for the artist-name wordmark." - **Album / release covers (one per release in section 8a's discography)** → `/public/generated/releases/{release-slug}.webp` · 1500×1500 · prompt: "per-release prompt: "Square album cover art in the visual register of section 7 for the release named in section 8a (album title + year). No on-image text — text will be composited in CSS. Subject derives from the release's tone (e.g. 'Glow' → soft amber light through silk; 'Slow Songs' → empty late-night diner counter)". One image per release." - **Tour-poster thumbnails (one per tour date in section 8a)** → `/public/generated/tour/{date-slug}.webp` · 1080×1350 · prompt: "per-date prompt: "Portrait-oriented tour poster background for the venue named on that date, evoking the city + venue character (e.g. Royal Festival Hall → Brutalist concrete + Thames at dusk). No on-image text — text composited in CSS."" - **Press / about portrait** → `/public/generated/about-portrait.webp` · 1200×1500 · prompt: "Editorial portrait of the artist named in section 8a, natural light, slight smile or thoughtful neutral, neutral background, suitable for an About page. No on-image text." - **Merch grid product shots (8 items)** → `/public/generated/merch/m-01.webp … m-08.webp` · 1200×1200 · prompt: "Per-item prompt: white-seamless studio shot of a single merch item — t-shirt, hoodie, vinyl sleeve, tote, enamel pin, poster, beanie, sticker pack — in the artist's palette. No on-image text. Real-photo aesthetic." - **Wordmark / monogram** → `/public/generated/wordmark.svg` · prompt: "A simple artist wordmark for the artist named in section 8a, set in the display sans/serif of section 7, no glow, suitable for tour-poster headers." 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-tour.webp` — 1024×1024 — prompt: "Minimal hand-drawn line illustration of an empty stage with one microphone stand, single-stroke outline, no colour fill." - `/public/samples/empty-state-discography.webp` — 1024×1024 — prompt: "Minimal hand-drawn line illustration of an empty vinyl sleeve, 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 `artists/{artistSlug}/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 - **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 `
