Xenotech Audio Blueprint

Required key.

Add this in your Lovable project under Settings → Secrets before pasting the prompt below.

Paste into a fresh Lovable project. Make sure the key above is set first. read the build strategy →

Build "Xenotech Audio Blueprint" as a ONE-SHOT Lovable build. The participant has only
5 credits — this single message must produce a working demo with no follow-ups.
Single-page TanStack Start app. Cut scope ruthlessly.

CONCEPT
Lovable AI describes alien tech so narrative designers build worlds; FLock generates SFX for it.
Discipline: Writing, Poetry & Narrative (sci-fi worldbuilding).
Recipe: FLock Image Generation (visual generation) as the single creative surface.
Why this kernel: Generative SFX allows narrative designers to instantly prototype futuristic, non-existent mechanical sounds directly from text descriptions.

LOVABLE BUDGET (HARD CAP: ONE-SHOT, ~5 CREDITS TOTAL):
The participant has FIVE Lovable credits for the whole build. This prompt MUST
ship a working demo on the FIRST message with zero follow-ups. Engineer for that.
- ONE TanStack Start app, ONE route (`src/routes/index.tsx`). No extra pages, no auth, no nav.
- ONE TanStack server function in `src/lib/flock.functions.ts` that proxies the FLock call.
- ONE client surface (a textarea + button, or chat box, or prompt-to-canvas) wired to it.
- NO database, NO Lovable Cloud, NO auth, NO file uploads, NO extra integrations.
- NO tests, NO docs pages, NO settings screens, NO theming toggles.
- Libraries: template defaults + `zod`. Nothing else.
- Keep the diff small enough to land in one build pass. If a feature is not on
  screen in the user flow below, do not build it. Cut scope before adding scope.

STACK
- TanStack Start app, the index route only.
- FLock.io is the only AI dependency. All API calls live inside a `createServerFn`
  handler so `FLOCK_API_KEY` stays on the server.
- Client surface fits the kernel: a prompt box that returns the result.
- Tailwind + shadcn. Editorial look: gold accent on a dark or warm-cream
  background, generous type, one strong headline, one primary action.
- Footer renders: "Built during the FLock.io Creative Hackathon organised by StreetKode Fam during Indian Krump Festival 14".

SERVER FUNCTION (src/lib/flock.functions.ts) — FLock image generation:
```ts
import { createServerFn } from "@tanstack/react-start";
import { z } from "zod";

/** Built during the FLock.io Creative Hackathon organised by StreetKode Fam during Indian Krump Festival 14 */
export const render = createServerFn({ method: "POST" })
  .inputValidator((d) => z.object({ brief: z.string().min(1).max(1000) }).parse(d))
  .handler(async ({ data }) => {
    // FLock image models are called via chat completions with the image modality.
    const r = await fetch("https://api.flock.io/v1/chat/completions", {
      method: "POST",
      headers: {
        "x-litellm-api-key": process.env.FLOCK_API_KEY!,
        "Content-Type": "application/json",
      },
      body: JSON.stringify({
        model: "nano-banana-2",
        modalities: ["image", "text"],
        messages: [{
          role: "user",
          content: `Concept art for sci-fi worldbuilding: ${data.brief}. Editorial, high detail.`,
        }],
      }),
    });
    if (r.status === 401) throw new Error("FLock rejected the API key — check FLOCK_API_KEY.");
    if (r.status === 402) throw new Error("FLock balance exhausted — top up at platform.flock.io.");
    if (r.status === 429) throw new Error("FLock rate limited — try again in a moment.");
    if (!r.ok) throw new Error(`FLock image failed: ${r.status}`);
    const j = await r.json();
    // FLock returns the image URL either as an `image_url` block or as a data URL
    // in the assistant message. Handle both.
    const msg = j.choices?.[0]?.message;
    const url = msg?.images?.[0]?.image_url?.url
             ?? msg?.content?.match?.(/https?:\/\/\S+\.(?:png|jpg|jpeg|webp)/i)?.[0];
    if (!url) throw new Error("FLock returned no image URL.");
    return { url: url as string };
  });
```

CLIENT: textarea + "Render" button. On success, show `<img src={url} />` and a
download link. Keep one canvas on screen, replace it on the next render.

FLock image-capable models: `nano-banana-2` (fast, default), `gemini-3.1-pro-preview`
(highest fidelity), `gemini-3-flash-preview` (balanced). Browse at
https://platform.flock.io/models.

USER FLOW (the entire app — nothing else exists)
1. Land on the page; the headline previews what the demo does for sci-fi worldbuilding.
2. The primary action (a prompt-driven canvas that renders covers, moodboards, posters or scene art on demand) is one tap away; the rest of the layout supports it.
3. FLock runs the kernel server-side, the result lands on screen, the user can retry or copy.

KEY — only ONE secret is required:
1. `FLOCK_API_KEY`. Sign up at https://platform.flock.io, create a team,
   generate an API key (starts with `sk-...`). Add it to Project Settings ->
   Secrets. Read it only on the server via `process.env.FLOCK_API_KEY`.
   Never prefix with `VITE_`, never expose to the client. One key unlocks
   the entire FLock model marketplace — text, image, video, tools.
